When max modify header action is zero, we return -EOPNOTSUPP
directly. In this way, we can ignore wrong message info (e.g.
"mlx5: parsed 0 pedit actions, can't do more").

This happens when offloading pedit actions on mlx VFs.

For example:
$ tc filter add dev mlx5_vf parent ffff: protocol ip prio 1 \
        flower skip_sw dst_mac 00:10:56:fb:64:e8 \
        dst_ip 1.1.1.100 src_ip 1.1.1.200 \
        action pedit ex munge eth src set 00:10:56:b4:5d:20

this command should work, we support header re-write (pedit offload) for tc NIC rules

Is this CX5 VF? if yes, something broke

No, this is cx4
