BRIDGE_VLAN_FILTERING automatically adds a newly bridged port to the
VLAN with the bridge's default_pvid.
The mv88e6xxx driver currently reserves VLANs 4000+ for unbridged ports
isolation. When a port joins a bridge, it leaves its reserved VLAN. When
a port leaves a bridge, it joins again its reserved VLAN.
But if the VLAN filtering is disabled, or if this hardware VLAN is
already in use, the bridged port ends up with no default VLAN, and the
communication with the CPU is thus broken.
To fix this, make a port join its reserved VLAN once on setup, never
leave it, and restore its PVID after another one was eventually used.

The current bridge code calls switchdev_port_obj_del on a VLAN port even
if the corresponding switchdev_port_obj_add call returned -EOPNOTSUPP.
If the DSA driver doesn't return -EOPNOTSUPP for a software port VLAN in
its port_vlan_del function, the VLAN is not deleted. Unbridging the port
also generates a stack trace for the same reason.
This can be quickly tested on a VLAN filtering enabled system with:
# brctl addbr br0
# brctl addif br0 lan0
# brctl addbr br1
# brctl addif br1 lan1
# brctl delif br1 lan1
Both bridges have a default default_pvid set to 1. lan0 uses the
hardware VLAN 1 while lan1 falls back to the software VLAN 1.
Unbridging lan1 does not delete its software VLAN, and thus generates
the following stack trace:
[ 2991.681705] device lan1 left promiscuous mode
[ 2991.686237] br1: port 1(lan1) entered disabled state

We probably need to restore needed_headroom setting (but shrunk to

space. In theory, it should not give us performance penalty.

When stopping the port, the CPU notifier are still there whereas the
mvneta_stop_dev function calls mvneta_percpu_disable() on each CPUs.
It was possible to have a new CPU coming at this point which could be
racy.
This patch adds a flag preventing executing the code notifier for a new
CPU when the port is stopping. It also uses the spinlock introduces
previously. To avoid the deadlock, the lock has been moved outside the
mvneta_percpu_elect function.

Electing a CPU must be done in an atomic way: it should be done after or
before the removal/insertion of a CPU and this function is not reentrant.
During the loop of mvneta_percpu_elect we associates the queues to the
CPUs, if there is a topology change during this loop, then the mapping
between the CPUs and the queues could be wrong. During this loop the
interrupt mask is also updating for each CPUs, It should not be changed
in the same time by other part of the driver.
This patch adds spinlock to create the needed critical sections.

In the MVNETA_INTR_* registers, the queues related fields are per cpu,
according to the datasheet (comment in [] are added by me):
"In a multi-CPU system, bits of RX[or TX] queues for which the access by
the reading[or writing] CPU is disabled are read as 0, and cannot be
cleared[or written]."
That means that each time we want to manipulate these bits we had to do
it on each cpu and not only on the current cpu.

Instead of using a for_each_* loop in which we just call the
smp_call_function_single macro, it is more simple to directly use the
on_each_cpu macro. Moreover, this macro ensures that the calls will be
done all at once.

When passing to the management of multiple RX queue, the
mvneta_percpu_elect function was broken. The use of the modulo can lead
to elect the wrong cpu. For example with rxq_def=2, if the CPU 2 goes
offline and then online, we ended with the third RX queue activated in
the same time on CPU 0 and CPU2, which lead to a kernel crash.
With this fix, we don't try to get "the closer" CPU if the default CPU is
gone, now we just use CPU 0 which always be there. Thanks to this, the
code becomes more readable, easier to maintain and more predicable.

The current logic in bond_arp_rcv will accept an incoming ARP for
validation if (a) the receiving slave is either "active" (which includes
the currently active slave, or the current ARP slave) or, (b) there is a
currently active slave, and it has received an ARP since it became active.
For case (b), the receiving slave isn't the currently active slave, and is
receiving the original broadcast ARP request, not an ARP reply from the
target.
This logic can fail if there is no currently active slave. In
this situation, the ARP probe logic cycles through all slaves, assigning
each in turn as the "current_arp_slave" for one arp_interval, then setting
that one as "active," and sending an ARP probe from that slave. The
current logic expects the ARP reply to arrive on the sending
current_arp_slave, however, due to switch FDB updating delays, the reply
may be directed to another slave.
This can arise if the bonding slaves and switch are working, but
the ARP target is not responding. When the ARP target recovers, a
condition may result wherein the ARP target host replies faster than the
switch can update its forwarding table, causing each ARP reply to be sent
to the previous current_arp_slave. This will never pass the logic in
bond_arp_rcv, as neither of the above conditions (a) or (b) are met.
Some experimentation on a LAN shows ARP reply round trips in the
200 usec range, but my available switches never update their FDB in less
than 4000 usec.
This patch changes the logic in bond_arp_rcv to additionally
accept an ARP reply for validation on any slave if there is a current ARP
slave and it sent an ARP probe during the previous arp_interval.

Prior to 4.3, openvswitch tunnel vports (vxlan, gre and geneve) could
transmit vxlan packets of any size, constrained only by the ability to
send out the resulting packets. 4.3 introduced netdevs corresponding
to tunnel vports. These netdevs have an MTU, which limits the size of
a packet that can be successfully encapsulated. The default MTU
values are low (1500 or less), which is awkwardly small in the context
of physical networks supporting jumbo frames, and leads to a
conspicuous change in behaviour for userspace.
Instead, set the MTU on openvswitch-created netdevs to be the relevant
maximum (i.e. the maximum IP packet size minus any relevant overhead),
effectively restoring the behaviour prior to 4.3.

Allow the MTU of geneve devices to be set to large values, in order to
exploit underlying networks with larger frame sizes.
GENEVE does not have a fixed encapsulation overhead (an openvswitch
rule can add variable length options), so there is no relevant maximum
MTU to enforce. A maximum of IP_MAX_MTU is used instead.
Encapsulated packets that are too big for the underlying network will
get dropped on the floor.

Allow the MTU of vxlan devices without an underlying device to be set
to larger values (up to a maximum based on IP packet limits and vxlan
overhead).
Previously, their MTUs could not be set to higher than the
conventional ethernet value of 1500. This is a very arbitrary value
in the context of vxlan, and prevented vxlan devices from being able
to take advantage of jumbo frames etc.
The default MTU remains 1500, for compatibility.

Driver only needs to allocate for [ngpio / 32] controllers,
as each controller handles 32 gpios. But the current driver
allocates for ngpio of which the extra allocated are unused.
Fix it be registering only the required number of controllers.

Currently the first parameter of irq_domain_add_legacy is NULL.
irq_find_host function returns NULL when we do not populate the of_node
and hence irq_of_parse_and_map call fails whenever we want to request a
gpio irq. This fixes the request_irq failures for gpio interrupts.

A recent patch broke parsing the gain, offset, and threshold parameters
from device tree. Instead of setting the cached values and writing them
to the correct registers during probe, it would write the values from DT
into the register address variables and never write them to the chip
during normal operation.

Commit ae461131960b ("of: of_mdio: Add a whitelist of PHY

in OCTEON, for selected boards, the kernel DTB pruning code will overwrite
the DTB compatible string with "marvell,88e1145", which is missing
from the whitelist. Add it.

Firmware posts the devcmd result in result ring. In case of timeout, driver
does not increment the current result pointer and firmware could post the
result after timeout has occurred. During next devcmd, driver would be

tg3_tso_bug() can hit a condition where the entire tx ring is not big
enough to segment the GSO packet. For example, if MSS is very small,
gso_segs can exceed the tx ring size. When we hit the condition, it
will cause tx timeout.
tg3_tso_bug() is called to handle TSO and DMA hardware bugs.
For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet.
For DMA bugs, we can still fall back to linearize the SKB and let the
hardware transmit the TSO packet.
This patch adds a function tg3_tso_bug_gso_check() to check if there
are enough tx descriptors for GSO before calling tg3_tso_bug().
The caller will then handle the error appropriately - drop or
lineraize the SKB.

innocent enough that there was little reason to wait (const/
__initconst and Kconfig deps).
Quite a bit of the changes on OMAP were due to fixes to no longer
write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but
there were also other fixes.
Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC
