From edf15c17420fed108046da50b3d3ae53dfa0e0ae Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 4 May 2010 22:25:42 +0000 Subject: [PATCH] e1000e: increase rx fifo size to 36K on 82574 and 82583 This change increases the RX fifo size to 36K for standard frames and decreases the TX fifo size to 4K. The reason for this change is that on slower systems the RX is much more likely to backfill and need space than the TX is. As long as the TX fifo is twice the size of the MTU we should have more than enough TX fifo. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
