Subject: [PATCH net-next 5/6] qlcnic: Enable multiple Tx queue support for 83xx/84xx Series adapters.
From: Himanshu Madhani <himanshu.madhani@...gic.com>
o 83xx and 84xx firmware is capable of multiple Tx queues.
This patch will enable multiple Tx queues for 83xx/84xx
series adapters. Max number of Tx queues supported will be 8.
