From 1cbb1a61d59b7552e1e3fde485d8af5699fe16e0 Mon Sep 17 00:00:00 2001 From: Vasanthy Kolluri Date: Thu, 17 Feb 2011 13:57:19 +0000 Subject: [PATCH] enic: Always use single transmit and single receive hardware queues per device We believe that our earlier patch for supporting multiple hardware receive queues per enic device requires more internal testing. At this point, we think that it's best to disable the use of multiple receive queues. The current patch provides an effective means for the same. Also, we continue to disallow multiple hardware transmit queues per device. But change the way we enforce this in order to maintain consistency with the way receive queues are handled.
