Setting connection tracking OVS flows and then setting non-CT flows that
use tuple rewrite action (e.g. mod_tp_dst), causes the latter flows not
being offloaded.
Fix by using a stricter condition in modify_header_match_supported() to
check tuple rewrite support only for flows with CT action. The check is
factored out into standalone modify_tuple_supported() function to aid
readability.
Fixes: 7e36feeb0467 ("net/mlx5e: CT: Don't offload tuple rewrites for established tuples")

Device firmware doesn't handle ecpu bit for vhca state processing
events and commands. Instead device firmware refers to the unique
function id to distinguish SF of different PCI functions.
When ecpu bit is used, firmware returns a syndrome.
mlx5_cmd_check:780:(pid 872): MODIFY_VHCA_STATE(0xb0e) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x263211)
mlx5_sf_dev_table_create:248:(pid 872): SF DEV table create err = -22
Hence, avoid using ecpu bit.
