The RoCE v2 protocol exists on top of either the UDP/IPv4 or the UDP/IPv6 protocol: -------------------------------------------------------------- | L2 | L3 | UDP |IB BTH | Payload| ICRC | FCS | -------------------------------------------------------------- When a bond LAG netdev is in use, we would like to have the same hash result for RoCE packets as any other UDP packets, for this purpose we need to expose the bond_xmit_hash function to external modules. If no objection, I will push a patch that export this symbol. Thanks
