From 2b4a624d706d404a3edccb6d1bb2c440a6dbbc31 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Sun, 14 Sep 2008 14:09:59 +0200 Subject: [PATCH] mv643xx_eth: shrink default receive and transmit queue sizes Since the size of the receive queue is directly related to the data cache footprint of the driver (between refilling a receive ring entry with a fresh skb and receiving a packet in that entry, queue_size - 1 other skbs will have been touched), shrink the default receive queue size to a saner number of entries, as 400 is definite overkill for almost all workloads. While we are at it, trim the default transmit queue size a bit as well.
