Oops your right, new comprehensive patch, replacing the previous 2.

Fix bnx2 so that netpoll works properly.  Specifically:

1) Fix parameters to bnx2_interrupt to be a struct bnx2_napi rather than a
struct net_device

2) Fix poll_controller method to check every queue in the rx case so frames
aren't missed
