Yes, this is working. (awesome!)

As long as I only try to bring up the ib0.8001 interface. If I bring up
ib0, ib_ipoib freaks out and continuously prints (very rapidly):

ib0: multicast join failed for ff12:401b:7fff:0:0:0:ffff:ffff, status -22

I think this is an issue with IBSRM because pkey 7fff does not exist.  I
don't know whose fault this is.  IBSRM continuously prints:

mcast:  smc_mcast_process_add_request: Could not add member: status 0x600
mcast:  smc_mcast_check_new_group: Required components not set in comp_mask: required 0x00000000000130c6, set 0x0000000000010083 - mgid ff12401b7fff0000:00000000ffffffff
mcast:  smc_mcast_add_member: Could not verify attributes for new group: status 0x600

Bringing down ib0 stops the barrage.

Thanks,
