When deleting a VLAN device using an ioctl the netdev is unregistered
before the VLAN filter is updated via ndo_vlan_rx_kill_vid(). It can
lead to a use-after-free in mlxsw in case the VLAN device is deleted
while being enslaved to a bridge.
The reason for the above is that when mlxsw receives the CHANGEUPPER
event, it wrongly assumes that the VLAN device is no longer its upper
and thus destroys the internal representation of the bridge port despite
the reference count being non-zero.
Fix this by checking if the VLAN device is our upper using its real
device. In net-next I'm going to remove this trick and instead make
mlxsw completely agnostic to the order of the events.

GRE decap offload is configured when local routes prefix correspond to the
local address of one of the offloaded GRE tunnels. The matching check was
found to be too strict, such that for a flat GRE configuration, in which
the overlay and underlay traffic share the same non-default VRF, decap flow
was not offloaded.
Relax the check for decap flow offloading. A match occurs if the local
address of the tunnel matches the local route address while both share the
same VRF table.

It is possible to trigger a warning in mlxsw in case a flood entry which
mlxsw is not aware of is deleted from the VxLAN device. This is because
mlxsw expects to find a singly linked list where the flood entry is

When the ASIC detects that a unicast packet is routed through the same
router interface (RIF) from which it ingressed (iRIF == eRIF), it raises
a trap called loopback error (LBERROR).
Thus far, this trap was configured to send a sole copy of the packet to
the CPU so that ICMP redirect packets could be potentially generated by
the kernel.
This is problematic as the CPU cannot forward packets at 3.2Tb/s and
there are scenarios (e.g., "one-armed router") where iRIF == eRIF is not
an exception.
Solve this by changing the trap to send a copy of the packet to the CPU.
To prevent the kernel from forwarding the packet again, it is marked
with 'offload_l3_fwd_mark'.
The trap is configured in a trap group of its own with a dedicated
policer in order not to prevent packets trapped by other traps from
reaching the CPU.

Commit abf4bb6b63d0 ("skbuff: Add the offload_mr_fwd_mark field") added
the 'offload_mr_fwd_mark' field to indicate that a packet has already
undergone L3 multicast routing by a capable device. The field is used to
prevent the kernel from forwarding a packet through a netdev through
which the device has already forwarded the packet.
Currently, no unicast packet is routed by both the device and the
kernel, but this is about to change by subsequent patches and we need to
be able to mark such packets, so that they will no be forwarded twice.
Instead of adding yet another field to 'struct sk_buff', we can just
rename 'offload_mr_fwd_mark' to 'offload_l3_fwd_mark', as a packet
either has a multicast or a unicast destination IP.
While at it, add a comment about both 'offload_fwd_mark' and
'offload_l3_fwd_mark'.

payload in MCAM search.
NPC_AF_INTF(0..1)_KEX_CFG
NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG
NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG
NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG
Currently, the AF driver populates these registers to
configure the default values to address the most common
use cases such as key generation for channel number + DMAC.
The secure firmware stores different configuration
value of these registers to enable different NPC use case
along with the name for the lookup.
Patch loads profile binary from secure firmware over
the exiting CGX mailbox interface and apply the profile.
AF driver shall fall back to the default configuration
in case of any errors.
The AF consumer driver can know the selected profile
on response to NPC_GET_KEX_CFG mailbox by introducing
mkex_pfl_name in the struct npc_get_kex_cfg_rsp.

NIX_AF_LSO_FORMAT(0..31)_FIELD(0..7) register enables an SW defined
means to define LSO packet modification formats.
0..31 works as an index to choose the algorithm, On success, the mailbox
returns the index to the client of chosen LSO algorithm selection.
This index will be used in configuring the transmit descriptors.
Add mailbox interface to dynamically reserve and configure LSO format.
This commit also fixes 'sizem1' for NIX_LSOALG_TCP_FLAGS
to '1' i.e 2 Bytes.
