Since [1] flow API forbids usage of direction attributes in transfer
flow rules. This patch adapts mlx5 PMD to this requirement.
From this patch, flow rule validation in mxl5 PMD will reject transfer
flow rules with any of the direction attributes set
(i.e. 'ingress' or 'egress').
As a result flow rule can only have one of 'ingress', 'egress' or
'transfer' attributes set.
This patch also changes the following:
- Control flow rules used in FDB are 'transfer' only.
- Checks which assumed that 'transfer' can be used
with 'ingress' and 'egress' are reduced to just checking
for direction attributes, since all attributes are exclusive.
- Flow rules for updating flow_tag are created for both ingress
and transfer flow rules which have MARK action.
- Moves mlx5_flow_validate_attributes() function from generic flow
implementation to legacy Verbs flow engine implementation,
since it was used only there. Function is renamed accordingly.
Also removes checking if E-Switch uses DV in that
function, since if legacy Verbs flow engine is used,
then that is always not the case.
