4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arjun Vynipadath <arjun@xxxxxxxxxxx>
[ Upstream commit 843bd7db79c861b49e2912d723625f5fa8e94502 ]
When NetworkManager is enabled, there are chances that interface up
is called even before probe completes. This means we have not yet
allocated the FW sge queues, hence rest of ingress queue allocation
wont be proper. Fix this by calling setup_fw_sge_queues() before
register_netdev().
Fixes: 0fbc81b3ad51 ('chcr/cxgb4i/cxgbit/RDMA/cxgb4: Allocate resources dynamically for all cxgb4 ULD's')
