Does cxgbe support multiple processes mode? If not, how can we implement it?

I tried with 17.08 code, secondary process will crash at sge.c line 1098.
t4_eth_xmit()
because txq->eth_dev->data is NULL.

I am guessing cxgbe driver does not support multiple processes mode,
although I just need multiple tx in multiple processes.
