From 7d260ec26ee56495bcb32491d44ed4590cc838a0 Mon Sep 17 00:00:00 2001 From: Vasanthy Kolluri Date: Thu, 9 Jun 2011 10:37:02 +0000 Subject: [PATCH] enic: Get/Set interrupt resource index for transmit and receive queues Instead of deriving the index of a transmit/receive interrupt resource from the transmit/receive queue index, always save and retrieve it using an additional variable.
