Where does that EOPNOTSUPP come from? nxp_c45_mdo_add_rxsc from this
version of the code can't return that, and macsec_add_rxsc also
shouldn't at this point.
This is the source of -EOPNOTSUPP

Could you check which part of macsec_get_ops is failing? Since
macsec_newlink with "offload phy" worked, macsec_check_offload
shouldn't fail, so why does macsec_get_ops return NULL?
real_dev->phydev was NULL'ed?
