Earlier all poll routine can process rx and tx, But now one poll routine to process rx + tx and other for rx only. Last msix vector will be used for separate tx interrupt. o This is supported from fw version 4.4.2. o Bump version 5.0.5 Signed-off-by: Sony Chacko <schacko@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
