Does anyone know why this code exists in ipoib?
ipoib_port.c: ipoib_port_join_mcast()
/* Handle non IP mutlicast MAC addresses. */
/* Update the signature to use the lower 2 bytes of the OpenIB
OUI. */
mcast_req.member_rec.mgid.raw[2] = 0x14;
mcast_req.member_rec.mgid.raw[3] = 0x05;
/* Now copy the MAC address into the last 6 bytes of the GID. */
cl_memcpy( &mcast_req.member_rec.mgid.raw[10], mac.addr, 6 );
