From e154b639bbe53dc91d1873cd37d162bb2fe87aab Mon Sep 17 00:00:00 2001 From: Shreyas Bhatewara <sbhatewara@vmware.com> Date: Tue, 10 May 2011 06:13:56 +0000 Subject: [PATCH] vmxnet3: Use single tx queue when CONFIG_PCI_MSI not defined Resending this patch with few changes. Avoid multiple queues when MSI or MSI-X not available Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in the kernel. This will make number of tx and rx queues equal when MSI/X is not configured thus providing better performance.
