Printing misc interrupt status of hardware error event in the
IRQ handler is unnecessary, since hclge_handle_hw_msix_error()
will print out the detail information for this hardware error
when handling success. So, this patch removes the print in
IRQ handler, and prints it when hclge_handle_hw_msix_error()
fails.

The function netif_skb_features() will disable the TSO feature
by using dflt_features_check() if the driver does not implement
ndo_features_check ops, which may cause performance degradation
problem when hns3 hardware can do multiple tagged TSO.
Also, the HNS3 hardware only supports checksum on the SKB with
a max header len of 480 bytes, so remove the checksum and TSO
related features when the header len is over 480 bytes.

When uninitializing CMDQ, HCLGE_STATE_CMD_DISABLE will
be set up firstly, then the driver does not send command
anymore. So, hclge_free_cmd_desc can be called without
holding ring->lock. hclge_destroy_cmd_queue() and
hclge_destroy_queue() are unnecessary now, so removes them,
the VF driver has implemented currently.
BTW, the VF driver should set up HCLGEVF_STATE_CMD_DISABLE
as well in the hclgevf_cmd_uninit(), just likes what the PF
driver does.

A BD with FE bit means that it is the last BD of a packet,
currently the FE bit is checked before calling hns3_add_frag(),
which is unnecessary because the FE bit may have been checked
in some case.

after processing the first BD of a SKB and adjust the location
of memcpy() to reduce duplication.

To enable iproute2/tipc to generate backwards compatible
printouts and validate command parameters for nodes using a
<z.c.n> node address, it needs to be able to read the legacy
address flag from the kernel. The legacy address flag records
the way in which the node identity was originally specified.
The legacy address flag is requested by the netlink message
TIPC_NL_ADDR_LEGACY_GET. If the flag is set the attribute
TIPC_NLA_NET_ADDR_LEGACY is set in the return message.

VSOCK: add vsock_test test suite
The vsock_diag.ko module already has a test suite but the core AF_VSOCK
functionality has no tests. This patch series adds several test cases that
exercise AF_VSOCK SOCK_STREAM socket semantics (send/recv, connect/accept,
half-closed connections, simultaneous connections).
The v1 of this series was originally sent by Stefan.
v3:
- Patch 6:
* check the byte received in the recv_byte()
* use send(2)/recv(2) instead of write(2)/read(2) to test also flags
(e.g. MSG_PEEK)
- Patch 8:
* removed unnecessary control_expectln("CLOSED") [Stefan].
- removed patches 9,10,11 added in the v2
- new Patch 9 add parameters to list and skip tests (e.g. useful for vmci
that doesn't support half-closed socket in the host)
- new Patch 10 prints a list of options in the help
- new Patch 11 tests MSG_PEEK flags of recv(2)

- ar9331: fix register definition and add ASCII art switch documentation.
changes v6:
- rebase against net-next
changes v5:
- remote support for port5. The effort of using this port is

adding buggy support.
- remove port enable call back. There is nothing what we actually need

- rebase it against v5.5-rc1

- ag71xx: ag71xx_mac_validate fix always false comparison (&& -> ||)

- tag_ar9331: drop skb_set_mac_header()

supported by HW and SW.
- ag71xx: ag71xx_mac_validate: return all supported bits on
PHY_INTERFACE_MODE_NA
changes v2:
- move Atheros AR9331 TAG format to separate patch
- use netdev_warn_once in the tag driver to reduce potential message spam
- typo fixes
- reorder tag driver alphabetically
- configure switch to maximal frame size
- use mdiobus_read/write
- fail if mdio sub node is not found
- add comment for post reset state
- remove deprecated comment about device id
- remove phy-handle option for node with fixed-link
- ag71xx: set 1G support only for GMII mode
This patch series provides dsa switch support for Atheros ar9331 WiSoC.

driver (as well phylink based) work properly.

net: bcmgenet: Turn on offloads by default
This commit stack is based on Florian's commit 4e8aedfe78c7 ("net:
systemport: Turn on offloads by default") and enables the offloads for
the bcmgenet driver by default.
The first commit adds support for the HIGHDMA feature to the driver.
The second converts the Tx checksum implementation to use the generic
hardware logic rather than the deprecated IP centric methods.
The third modifies the Rx checksum implementation to use the hardware
offload to compute the complete checksum rather than filtering out bad
packets detected by the hardware's IP centric implementation. This may
increase processing load by passing bad packets to the network stack,
but it provides for more flexible handling of packets by the network
stack without requiring software computation of the checksum.
The remaining commits mirror the extensions Florian made to the sysport
driver to retain symmetry with that driver and to make the benefits of
the hardware offloads more ubiquitous.

In preparation for unconditionally enabling TX and RX checksum
offloads, refactor bcmgenet_set_features() a bit such that
__netdev_update_features() during register_netdev() can make sure
that features are correctly programmed during network device
registration.
Since we can now be called during register_netdev() with clocks
gated, we need to temporarily turn them on/off in order to have a
successful register programming.
We also move the CRC forward setting read into
bcmgenet_set_features() since priv->crc_fwd_en matters while
turning on RX checksum offload, that way we are guaranteed they
are in sync in case we ever add support for NETIF_F_RXFCS at some
point in the future.

The simple RX resync strategy controlled by the kernel does not
guarantee as good results as if the device helps by detecting
the potential record boundaries and keeping track of them.
We've called this strategy stream scan in the tls-offload doc.
Implement this strategy for the NFP. The device sends a request
for record boundary confirmation, which is then recorded in
per-TLS socket state and responded to once record is reached.
Because the device keeps track of records passing after the
request was sent the response is not as latency sensitive as
when kernel just tries to tell the device the information
about the next record.

Extend the notifier to track IPv6 route changes and create a new list that

Handle this request by doing a route lookup on the IPv6 address and

The IPv4 set tunnel action allows the setting of tunnel metadata such as

address and is used to calculate the next hop from from the neighbour
table.
Much of the IPv4 tunnel actions can be reused for IPv6 tunnels. Change the
names of associated functions and structs to remove the IPv4 identifier
and make minor modifcations to support IPv6 tunnel actions.
Ensure the pre-tunnel action contains the IPv6 address along with an
