From Patrisious:

This series extends previously added MACsec offload support
to cover RoCE traffic either.

In order to achieve that, we need configure MACsec with offload between
the two endpoints, like below:

REMOTE_MAC=10:70:fd:43:71:c0

* ip addr add 1.1.1.1/16 dev eth2
* ip link set dev eth2 up
* ip link add link eth2 macsec0 type macsec encrypt on
* ip macsec offload macsec0 mac
* ip macsec add macsec0 tx sa 0 pn 1 on key 00 dffafc8d7b9a43d5b9a3dfbbf6a30c16
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC sa 0 pn 1 on key 01 ead3664f508eb06c40ac7104cdae4ce5
* ip addr add 10.1.0.1/16 dev macsec0 
* ip link set dev macsec0 up

And in a similar manner on the other machine, while noting the keys order
would be reversed and the MAC address of the other machine.

RDMA traffic is separated through relevant GID entries and in case of IP ambiguity
issue - meaning we have a physical GIDs and a MACsec GIDs with the same IP/GID, we
disable our physical GID in order to force the user to only use the MACsec GID.

Thanks
