This bug has been copied from bug #576709 and has been proposed
to be backported to 5.4 z-stream (EUS).
Please cancel this request for 5.4.z.
The fnic tx_flush bug fix is applicable only to 5.5 kernel. The 5.4
kernel does not have FIP support, and this bug crept in when we added
FIP support in the 5.5 in-box driver.
