net/mlx5e: Advertise mlx5 ethernet driver updates sk_buff md_dst for MACsec 

stable inclusion
from stable-v6.6.30
commit 57c34bf73128e25823354f41e9f845dc9aa1f3c6
bugzilla: https://gitee.com/openeuler/kernel/issues/I9MPZ8

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=57c34bf73128e25823354f41e9f845dc9aa1f3c6



--------------------------------

commit 39d26a8f2efcb8b5665fe7d54a7dba306a8f1dff upstream.

mlx5 Rx flow steering and CQE handling enable the driver to be able to
update an skb's md_dst attribute as MACsec when MACsec traffic arrives when
a device is configured for offloading. Advertise this to the core stack to
take advantage of this capability.
