From 3bf517df0d99f1cf5d369c73ab68e0afe6a3c2f9 Mon Sep 17 00:00:00 2001 From: Himanshu Madhani Date: Mon, 16 Dec 2013 15:36:57 -0500 Subject: qlcnic: Fix diagnostic test for all adapters. o Driver should re-allocate all Tx queues after completing diagnostic tests. This regression was added by commit id c2c5e3a0681bb1945c0cb211a5f4baa22cb2cbb3 ("qlcnic: Enable diagnostic test for multiple Tx queues.") Signed-off-by: Himanshu Madhani Signed-off-by: David S.

This patch fixes this validation and would fail set_channel operation if any of these ring value is 0.
