Hi,
Did you check the option to hold the netif_tx_lock_xxx() in
ipoib_cm_rep_handler function (over the line
set_bit(IPOIB_FLAG_OPER_UP)) instead of in the send data path flow?
That does seem better, then the test_bit in the datapath could become
non-atomic too :)

Thanks for the feedback! I've not tried that but I certainly can.
