-Subject: bnx2x: tx_has_work should not wait for FW
-Acked-by: Karsten Keil <kkeil@novell.com>
-Reference: bnc#472500
-
-The current tx_has_work waited until all packets sent by the driver
-are marked as completed by the FW. This is too greedy and it causes
-the bnx2x_poll to spin in vain. The driver should only check that all
-packets FW already completed are freed - only in unload flow the
-driver should make sure that transmit queue is empty
