From 7e3b4ffb38b550b42c3868cffedb734c3a507073 Mon Sep 17 00:00:00 2001 From: Koki Sanagi Date: Wed, 15 Feb 2012 14:45:39 +0000 Subject: [PATCH] igb: output register's information related to RX/TX queue[4-15] Current igb outputs registers related to TX/RX queues(ex. RDT, RDH, TDT, TDH). But it thinks the number of RX/TX queues is 4. But 82576 has 16 RX/TX queues. This patch modifies igb to output the rest of the registers if the device is 82576.
