From 2601d8a0049c8b5d29cd5adb844a305a804e505f Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Sat, 5 Jun 2010 17:24:33 +0000 Subject: [PATCH] tg3: Off-by-one error in RSS setup The driver was incorrectly programming the indirection table such that rx traffic intended for the second ring went to the first ring, rx traffic intended for the third ring went to the second ring, etc. This patch changes the code so that rx traffic is diverted to the proper ring.
