Here is the list of the MAC capabilities specific to the particular DW MAC
IP-cores currently supported by the driver:
DW MAC100: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_10 | MAC_100
DW GMAC: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_10 | MAC_100 | MAC_1000
Allwinner sun8i MAC: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_10 | MAC_100 | MAC_1000
DW QoS Eth: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_10 | MAC_100 | MAC_1000 | MAC_2500FD
if there is more than 1 active Tx/Rx queues:
MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_10FD | MAC_100FD | MAC_1000FD | MAC_2500FD
DW XGMAC: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_1000FD | MAC_2500FD | MAC_5000FD | MAC_10000FD
DW XLGMAC: MAC_ASYM_PAUSE | MAC_SYM_PAUSE |
MAC_1000FD | MAC_2500FD | MAC_5000FD | MAC_10000FD |
MAC_25000FD | MAC_40000FD | MAC_50000FD | MAC_100000FD
As you can see there are only two common capabilities:
MAC_ASYM_PAUSE | MAC_SYM_PAUSE.
Meanwhile what is currently implemented defines 10/100/1000 link speeds
for all IP-cores, which is definitely incorrect for DW MAC100, DW XGMAC
and DW XLGMAC devices.
Seeing the flow-control is implemented as a callback for each MAC IP-core
(see dwmac100_flow_ctrl(), dwmac1000_flow_ctrl(), sun8i_dwmac_flow_ctrl(),
etc) and since the MAC-specific setup() method is supposed to be called
for each available DW MAC-based device, the capabilities initialization
can be freely moved to these setup() functions, thus correctly setting up
the MAC-capabilities for each IP-core (including the Allwinner Sun8i). A
new stmmac_link::caps field was specifically introduced for that so to
have all link-specific info preserved in a single structure.
Note the suggested change fixes three earlier commits at a time. The
commit 5b0d7d7da64b ("net: stmmac: Add the missing speeds that XGMAC
supports") permitted the 10-100 link speeds and 1G half-duplex mode for DW
XGMAC IP-core even though it doesn't support them. The commit df7699c70c1b
("net: stmmac: Do not cut down 1G modes") incorrectly added the MAC1000
capability to the DW MAC100 IP-core. Similarly to the DW XGMAC the commit
8a880936e902 ("net: stmmac: Add XLGMII support") incorrectly permitted the
10-100 link speeds and 1G half-duplex mode for DW XLGMAC IP-core.
Fixes: 5b0d7d7da64b ("net: stmmac: Add the missing speeds that XGMAC supports")
Fixes: df7699c70c1b ("net: stmmac: Do not cut down 1G modes")
Fixes: 8a880936e902 ("net: stmmac: Add XLGMII support")

The stmmac has the possibility to automatically strip the padding/FCS for IEEE
802.3 type frames. This feature is enabled conditionally. Therefore, the stmmac
receive path has to have a determination logic whether the FCS has to be
stripped in software or not.
In fact, for DSA this ACS feature is disabled and the determination logic
doesn't check for it properly. For instance, when using DSA in combination with
an older stmmac (pre version 4), the FCS is not stripped by hardware or software
which is problematic.
So either add another check for DSA to the fast path or simply disable ACS
feature completely. The latter approach has been chosen, because most of the
time the FCS is stripped in software anyway and it removes conditionals from the
receive fast path.

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.

Move all the core version detection to a common place ("hwif.c") and
implement a table which can be used to lookup the correct callbacks for
each IP version.
This simplifies the initialization flow of each IP version and eases
future implementation of new IP versions.

Broadcom tags inserted by Broadcom switches put a 4 byte header after
the MAC SA and before the EtherType, which may look like some sort of 0
length LLC/SNAP packet (tcpdump and wireshark do think that way). With
ACS enabled in stmmac the packets were truncated to 8 bytes on
reception, whereas clearing this bit allowed normal reception to occur.
In order to make that possible, we need to pass a net_device argument to
the different core_init() functions and we are dependent on the Broadcom
tagger padding packets correctly (which it now does). To be as little
invasive as possible, this is only done for gmac1000 when the network
device is DSA-enabled (netdev_uses_dsa() returns true).

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.
So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.
So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.
In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.

Two different set_mac functions exists but stmmac_dwmac4_set_mac() is
only used for enabling and never for disabling.
So on dwmac4, the MAC RX/TX is never disabled.
This patch add a generic function pointer set_mac() to stmmac_ops and
replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to
this pointer.
Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops
is duplioacted like dwmac4_dma_ops.

The stmmac driver have two methods for registers dumps: via ethtool and
at init (if NETIF_MSG_HW is enabled).
It is better to keep only one method, ethtool, since the other was ugly.

"fill the reg_space used by ethtool".

This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case #8000684337 and shared with the maintainer.

This patch removes the check for the number of mulitcast addresses
when using hash based filtering since it's not necessary. If the number
of multicast addresses in the list exceeds the number of multicast hash
bins, the bins will "fold" over into one of the bins configured and
enabled for the particular component instance.
The default number of maximum unicast addresses was changed from 32 to 1
since this number is not dependent on the component revision. The maximum
number of multicast and unicast addresses is dependent on the configuration
of the Synopsys EMAC configured by the SOC architect at the time the
features were selected and configured for a particular component. Sadly,
Synopsys does not provide a way to query the precise number supported
by a particular component, so we must fall back on a devicetree entry.
This configuration could vary from vendor to vendor (such as STMicro,
Altera, etc).
The multicast bins are set for every possible filtering case (including
no entries) - previously the bits were set only if multicast filter entries
were present.

The synopsys EMAC can be configured for different numbers of multicast hash
bins and perfect filter entries at device creation time and there's no way
to query this configuration information at runtime. As a result, a devicetree
parameter is required in order for the driver to program these filters
correctly for a particular device instance. This patch modifies the
10/100/1000 MAC software interface such that these configuration parameters
can be set at initialization time.

These changes correct the following issues with jumbo frames on the
stmmac driver:
1) The Synopsys EMAC can be configured to support different FIFO
sizes at core configuration time. There's no way to query the
controller and know the FIFO size, so the driver needs to get this
information from the device tree in order to know how to correctly
handle MTU changes and setting up dma buffers. The default
max-frame-size is as currently used, which is the size of a jumbo
frame.
2) The driver was enabling Jumbo frames by default, but was not allocating
dma buffers of sufficient size to handle the maximum possible packet
size that could be received. This led to memory corruption since DMAs were
occurring beyond the extent of the allocated receive buffers for certain types
of network traffic.

Prior this patch, the internal debugging was based on ifdef
and also some printk were useless because many info are exposed
via ethtool.
This patch remove all the ifdef defines and now we only use
netif_msg_XXX levels.

This patch tidies up the code. I have run Linden (and verified with checkpatch)
many part of the driver trying to reorganize some sections respecting the
codying-style rules in the points where it was not done.

This patch starts adding in the main ISR the management of the PCS and
RGMII/SGMII core interrupts. This is to help further development
on this area. Currently the core irq handler only clears the
PCS and S-R_MII interrupts and reports the event in the ethtool stats.

This patch adds the Energy Efficient Ethernet support to the stmmac.
Please see the driver's documentation for further details about this support
in the driver.
Thanks also goes to Rayagond Kokatanur for his first implementation.
Note:
to clearly manage and expose the lpi interrupt status and eee ethtool
stats I've had to do some modifications to the driver's design and I
found really useful to move other parts of the code (e.g. mmc irq stat)
in the main directly. So this means that some core has been reworked
to introduce the EEE.
v1: initial patch
v2: fixed some sparse issues (typos)
v3: erroneously sent the v2 renamed as v3
v4:
o Fixed the return value of the stmmac_eee_init as suggested by D.Miller
o Totally reviewed the ethtool support for EEE
o Added a new internal parameter to tune the SW timer for TX LPI.
v5: do not change any eee setting in case of the stmmac_ethtool_op_set_eee fails
(it has to return -EOPNOTSUPP in that case).

This patch is to extend the number of MAC address registers
for 16 to 32. In fact, other new 16 registers are available in new
chips and this can help on perfect filter mode for unicast.
This patch also fixes the perfect filtering mode by setting the
bit 31 in the MAC address registers.
v2: fixed Coding Style.

This patch sanities the RX coe and adds the Type-1 Rx checksum offload engine (COE).
So the RX COE can be passed through the platform but can be fixed
at run-time in case of the core has the HW capability register.
Also to support the Type-1 Rx COE the driver must append the
HW checksum at the end of payload in case the Rx checksum
engine was used to offload the HW checksum.
This v2 version also fixes the IPC that has to be enabled and verified.

DWMAC Management Counters (MMC) are not fully support.
The minimal support added in the past allowed to
only disable counters (if present) and mask their
interrupts.
This patch prepares the driver to support the MMC
removing obsolete code.
