[openib-general] [PATCH]rmmod could crash in tx_ring[].skb & rx_ring[].skb.

[Shirley Ma]

I am going through the IPoIB code. I found rmmod could cause 
kernel crash. It's easy to fix tx_ring with tx_lock. rx_ring[].skb has 
the same problem, inducing another lock in ipoib_ib_handle_wc()
just for rmmod is too costly. Any other suggestion? 

Here is the patch for tx_ring[].skb.
