And what happens in this case?
ip link add link eth0 type macsec offload phy
ip link set eth0 down
ip macsec add macsec0 rx sci ...
ip macsec add macsec0 tx sa 0 ...
# etc
ip link set eth0 up
Will offload work with the current code?
(the interface was up before)
[root@alarm ~]# ip link add link end0 macsec0 type macsec encrypt on
offload phy
[root@alarm ~]# ip link set end0 down
[root@alarm ~]# ip macsec add macsec0 rx port 1 address

RTNETLINK answers: Operation not supported
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.
