In compat mode SIOC{G,S}IFBR ioctls were only supporting
BRCTL_GET_VERSION returning an artificially version to spur userland
tool to use SIOCDEVPRIVATE instead. But some userland tools ignore that
and use SIOC{G,S}IFBR unconditionally as seen with busybox's brctl.

Example of non working 32-bit brctl with CONFIG_COMPAT=y:
$ brctl show
brctl: SIOCGIFBR: Invalid argument

Example of fixed 32-bit brctl with CONFIG_COMPAT=y:
$ brctl show
bridge name     bridge id               STP enabled     interfaces

The blamed commit changed the vlan used by the host ports to be 4095
instead of 0.
Because of this change the following issues are seen:
- when the port is probed first it was adding an entry in the MAC table
  with the wrong vlan (port->pvid which is default 0) and not HOST_PVID
- when the port is removed from a bridge, it was using the wrong vlan to
  add entries in the MAC table. It was using the old PVID and not the
  HOST_PVID

This patch fixes this two issues by using the HOST_PVID instead of
port->pvid.

If NETIF_F_GRO_HW is disabled, the existing driver code uses kmalloc'ed
data for RX buffers.  This causes inefficient SW GRO performance
because the GRO data is merged using the less efficient frag_list.
Use netdev_alloc_frag() and friends instead so that GRO data can be
merged into skb_shinfo(skb)->frags for better performance.

CQE coalescing mode is the same as the timer reset coalescing mode
on Broadcom devices.  Currently this mode is always enabled if it
is supported by the device.  Restructure the code slightly to support
dynamically changing this mode.

Add a flags field to struct bnxt_coal.  Initially, the CQE flag will
be set for the RX and TX side if the device supports it.  We need to
move bnxt_init_dflt_coal() to set up default coalescing until the
capability is determined.

Patches #1-#2 make vxlan.sh test more flexible and extend it for IPv6
Patches #3-#4 make vxlan_fdb_veto.sh test more flexible and extend it
for IPv6
Patches #5-#6 add tests for VxLAN flooding for different ASICs
Patches #7-#8 add test for VxLAN related traps and align the existing
test

Change the case that sends packets with "too short inner packet" to
include part of ethernet header, to make the trap to be triggered due to
the correct reason.

According to ASIC arch, the trap is triggered if overlay packet length is
less than 18B, and the minimum inner packet should include source MAC and
destination MAC.

Till now the case passed because one of the reserved bits in VxLAN
header was used. This issue was found while adding an equivalent test
for IPv6.

The test configures VxLAN with IPv6 underlay and verifies that the
expected traps are triggered under the right conditions.

The test is similar to the existing IPv4 test.

The device stores flood records in a singly linked list where each
record stores up to X IP addresses of remote VTEPs.

The number of records is changed according to ASIC type and address
family.

Add a test which is similar to the existing IPv4 test to check IPv6.
The test is dedicated for Spectrum-2 and above, which support up to four
IPv6 addresses in one record.

The test verifies that packets are correctly flooded in various cases such
as deletion of a record in the middle of the list.

Add test to verify FDB vetos of VxLAN with IPv6 underlay.
Use the existing test which checks IPv4.

vxlan_fdb_veto.sh cases are dedicated to test VxLAN with IPv4 underlay.
The main changes to test IPv6 underlay are IP addresses and some flags.

Add variables to define all the values which supposed to be different
for IPv6 testing, set them to use the existing values by default.

The next patch will define the new added variables in a separated file,
so the same tests can be used for IPv6 also.

Use the existing test which checks IPv4.

Add separated test cases for learning which is not supported for IPv6
and for UDP checksum flags which are different from IPv4 flags.

equivalent functions for IPv6.
