From: Jiawei Wang @ 2022-11-02 13:44 UTC (permalink / raw)
  To: viacheslavo, matan; +Cc: dev, rasland, stable

The metadata register C value was lost in FDB egress while doing the
flow sampler on ConnectX-5. The FDB direction checking was decided by
the source port in the flow creation. If there's additional port item
was added in the flow match, then the actual source port was changed.

This patch adds the checking for the port id item:
RTE_FLOW_ITEM_TYPE_PORT_ID, RTE_FLOW_ITEM_TYPE_REPRESENTED_PORT,
and RTE_FLOW_ITEM_TYPE_PORT_REPRESENTOR,
then updates FDB egress checking and the source vport metadata
from the port item, also updates the PUSH VLAN, POP VLAN and
flow sampler action validation.

Fixes: 04c0d3f20f54 ("net/mlx5: fix port matching in sample flow rule")
Fixes: 255b8f86eb6e ("net/mlx5: fix E-Switch egress mirror flow validation")

While the ASO action(AGE, CT) with the sample action in the one
E-switch mirror flow, due to hardware limitation, the ASO action
after the sample action was not supported.

This patch adds the checking for this validation and reject the flows
with aso action after sample.
