cxgb3: fix crash due to manipulating queues before registration
Nishanth Aravamudan [Wed, 27 Oct 2010 19:06:30 +0000 (19:06 +0000)]
Along the same lines as "cxgb4: fix crash due to manipulating queues
before registration" (8f6d9f40476895571df039b6f1f5230ec7faebad), before
commit "net: allocate tx queues in register_netdevice"
netif_tx_stop_all_queues and related functions could be used between
device allocation and registration but now only after registration.
cxgb4 has such a call before registration and crashes now.  Move it
after register_netdev.
