The driver uses __napi_schedule_irqoff() which is fine as long as it is
invoked with disabled interrupts by everybody. Since the commit
mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
context. This may lead to list corruption if another driver uses
__napi_schedule_irqoff() in IRQ context.
Use __napi_schedule() which safe to use from IRQ and softirq context.

After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa:
configure the MTU for switch ports") my Lamobo R1 platform which uses
an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail
by rejecting a MTU of 1536. The reason for that is that the DMA
capabilities are not readable on this version of the IP, and there
is also no 'tx-fifo-depth' property being provided in Device Tree. The
property is documented as optional, and is not provided.
Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so
provide these values through platform data as an immediate fix until
various Device Tree sources get updated accordingly.

To rehash a previous explanation given in commit 1c44ce560b4d ("net:
mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is
up"), the switch driver operates the in a mode where a single VLAN can
be transmitted as untagged on a particular egress port. That is the
"native VLAN on trunk port" use case.
The configuration for this native VLAN is driven in 2 ways:
- Set the egress port rewriter to strip the VLAN tag for the native
VID (as it is egress-untagged, after all).
- Configure the ingress port to drop untagged and priority-tagged
traffic, if there is no native VLAN. The intention of this setting is
that a trunk port with no native VLAN should not accept untagged
traffic.
Since both of the above configurations for the native VLAN should only
be done if VLAN awareness is requested, they are actually done from the
ocelot_port_vlan_filtering function, after the basic procedure of
toggling the VLAN awareness flag of the port.
But there's a problem with that simplistic approach: we are trying to
juggle with 2 independent variables from a single function:
- Native VLAN of the port - its value is held in port->vid.
- VLAN awareness state of the port - currently there are some issues
here, more on that later*.
The actual problem can be seen when enslaving the switch ports to a VLAN
filtering bridge:
0. The driver configures a pvid of zero for each port, when in
standalone mode. While the bridge configures a default_pvid of 1 for
each port that gets added as a slave to it.
1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true.
The VLAN-filtering-dependent portion of the native VLAN
configuration is done, considering that the native VLAN is 0.
2. The bridge calls ocelot_vlan_add with vid=1, pvid=true,
untagged=true. The native VLAN changes to 1 (change which gets
propagated to hardware).
3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the
VLAN-filtering-dependent portion of the native VLAN configuration,
for the new native VLAN of 1. One can notice that after toggling "ip
link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0
type bridge vlan_filtering 1", the new native VLAN finally makes it
through and untagged traffic finally starts flowing again. But
obviously that shouldn't be needed.
So it is clear that 2 independent variables need to both re-trigger the
native VLAN configuration. So we introduce the second variable as
ocelot_port->vlan_aware.
*Actually both the DSA Felix driver and the Ocelot driver already had
each its own variable:
- Ocelot: ocelot_port_private->vlan_aware
- Felix: dsa_port->vlan_filtering
but the common Ocelot library needs to work with a single, common,
variable, so there is some refactoring done to move the vlan_aware
property from the private structure into the common ocelot_port
structure.

Fixes CT entries list corruption.
After allowing parallel insertion/removals in upper nf flow table
layer, unprotected ct entries list can be corrupted by parallel add/del
on the same flow table.
CT entries list is only used while freeing a ct zone flow table to
go over all the ct entries offloaded on that zone/table, and flush
the table.
As rhashtable already provides an api to go over all the inserted entries,
fix the race by using the rhashtable iteration instead, and remove the list.

On some SoCs, such as the i.MX6, it is necessary to set a bit
in the SoC level GPR register before suspending for wake on lan
to work.
The fec platform callback sleep_mode_enable was intended to allow this
but the platform implementation was NAK'd back in 2015 [1]
This means that, currently, wake on lan is broken on mainline for
the i.MX6 at least.
So implement the required bit setting in the fec driver by itself
by adding a new optional DT property indicating the GPR register
and adding the offset and bit information to the driver.

rec->llc is currently being assigned twice, once with the lower 8 bits
from packed_record[8] and then re-assigned afterwards with data from
packed_record[9]. This looks like a type, I believe the second assignment
should be using the |= operator rather than a direct assignment.

"The majority of the patches are cleanups, refactorings and clarity
improvements.
This cycle saw some more activity from Syzkaller, I think we are now
clean on all but one of those bugs, including the long standing and
obnoxious rdma_cm locking design defect. Continue to see many drivers
getting cleanups, with a few new user visible features.

cxgb4_update_mac_filt() earlier requests firmware to add a new MAC
address into MPS TCAM. The MPS TCAM index returned by firmware is
stored in pi->xact_addr_filt. However, the saved MPS TCAM index gets
overwritten again with the return value of cxgb4_update_mac_filt(),
which is wrong.
When trying to update to another MAC address later, the wrong MPS TCAM
index is sent to firmware, which causes firmware to return error,
because it's not the same MPS TCAM index that firmware had sent
earlier to driver.
So, fix by removing the wrong overwrite being done after call to
cxgb4_update_mac_filt().

Some packet traps are currently exposed to user space as being member of
"l3_drops" trap group, but internally they are member of a different
group.
Switch these traps to use the correct group so that they are all subject
to the same policer, as exposed to user space.
Set the trap priority of packets trapped due to loopback error during
routing to the lowest priority. Such packets are not routed again by the
kernel and therefore should not mask other traps (e.g., host miss) that
should be routed.
