This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

In tunnel encap we prepare the encap header for IPv4/6 cases, in two
separate functions. For ETH header generation the code is almost
duplicated.
Move the ETH header generation code from IPv4/6 functions to a helper
function, with no functional change.

Currently we don't support nor fail attempts to offload encap flows routed
to vlan device on the underlay network. We wrongly consider a vlan underlay
device to be on the same e-switch b/c the switchdev ID is retrieved recursively.
Add explicit check for that and fail such attempts.
Also align to a more strict check for the ingress and the underlay devices
to practically be on the same eswitch.

With the introduction of SR-IOV LAG, checking whether LAG is active
is no longer good enough, since RoCE and SR-IOV LAG each entails
different behavior by both the core and infiniband drivers.
This patch introduces facilities to discern LAG type, in addition to
mlx5_lag_is_active(). These are implemented in such a way as to allow
more complex mode combinations in the future.

When the uplink representors are put into lag, set all the
representors (VFs and uplinks) of the same NIC to return the same
switchdev id.
Currently, the route lookup code on the encapsulation offload path
assumes that same switchdev id for the source and dest devices means
that the dest is also mlx5 HW netdev. This doesn't hold anymore when we
align the switchdev Id of the uplinks to be same, which in turn causes
the bond/team to return that id to the caller. As such, enhance the
relevant check to take into account the uplink lag case.
