Subject: [PATCH] cxgb4vf: fix crash due to manipulating queues before registration
Date: Thu, 28 Oct 2010 13:16:47 -0700 [thread overview]
Message-ID: <1288297007-663-1-git-send-email-leedom@chelsio.com> (raw)
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.
