In mlx5 HW, encapsulation is offloaded by the steering rule having
index into an encapsulation table containing the entire set of headers
to be added by the HW. The driver sets these headers in a buffer when we
are offloading the action.

The code maintains mlx5_encap_entry for each encap header it has
encountered when attempted to offload TC tunnel set action.

This entry maintains a linked list of all the flows sharing the same
encap header, when the last flow is removed from the list the encap
entry is removed.

The actual encap_header is allocated by the driver in the hardware only
if we have layer two neighbour info when the encap entry is created.
While the flow is in the driver, the driver holds a reference on the
neighbour.

When a new flow with encap action is inserted, the code first checks if
the required encap entry exists according to the tunnel set parameters.
If it does the encap is shared, otherwise a new mlx5_encap_entry is
created.

TC action parsing implementation in the driver assumes that tunnel set
action is provided in the same order set by the user, e.g before the
mirred_redirect action.

By implementing this ndo, the host stack will set the vxlan udp port
also to VF representor netdevices. This will allow the TC offload code
in the driver when it gets a tunnel key set action to identify the UDP
port as vxlan, and hence the rule will be a candidate for offloading.

Driver uses a union for copying data to & from management firmware
when interacting with it.
Problem is that the function always copies sizeof(union) while commit
2edbff8d ("qed: Learn resources from management firmware") is casting
a union elements which is of smaller size [24-byte instead of 88-bytes].

Also, the union contains some inappropriate elements which increase its
size [should have been 32-bytes]. While this shouldn't corrupt other
PF messages to the MFW [as management firmware enforces permissions so
that each PF is allowed to write only to its own mailbox] we fix this
here as well.
