From f3e3ccf83bab261c5b55623bd3e9d1147b1c2e19 Mon Sep 17 00:00:00 2001 From: Manish Chopra Date: Thu, 2 Jan 2014 13:38:44 -0500 Subject: [PATCH] qlcnic: Fix resource allocation for TX queues o TX queues allocation was getting distributed equally among all the functions of the port including VFs and PF. Which was leading to failure in PF's multiple TX queues creation. o Instead of dividing queues equally allocate one TX queue for each VF as VF doesn't support multiple TX queues.
