Using dev_kfree_skb_any() will resolve the below issue when a
netconsole message is transmitted in an irq.

This is absolutely not the correct fix.

The netpoll facility must invoke ->poll() in an environment which
is compatible, locking and interrupt/soft-interrupt wise, as that
in which it is normally called.

Therefore, bnx2_tx_int(), which is invoked from the driver's ->poll()
method, should not need to use dev_kfree_skb_any().  The real problem
is somewhere else.
