Using dev_queue_xmit causes a system halt problem.

Hi all,

I use netfilter to hook packets at the NF_INET_LOCAL_OUT hook and send
the packets using dev_queue_xmit(). My module can successfully sends
packets. Unfortunately, the system always halts when my module is
installed. It seems that using dev_queue_xmit() causes an issue of a
deadlock. The problem is same when I use ndo_start_xmit() to send
packets. However, I am not sure what the exact problem is. May I know
how I can fix this problem. Thank you!

Best,
Lawrence
