1e62e222db2e ("net/mlx5: E-Switch, Use vport metadata matching only when mandatory")
---> In function esw_create_uplink_offloads_acl_tables, we now call esw_use_vport_metadata
instead of esw_check_vport_match_metadata_supported.
commit 748da30b376e034ae54b53e7e38e15cfa2bf4dda

net/mlx5: E-switch, Offloads shift ACL programming during enable/disable vport
Currently legacy mode enables ACL while enabling vport, while offloads
mode enable ACL when moving to offloads mode.
Bring consistency to both modes by enabling/disabling ACL when
enabling/disabling a vport.
It also eliminates creating ingress ACL table on unused ECPF vport in
offloads mode.
