Subject: [PATCH net-next] netxen: write IP address to firmware when using bonding
The following patch was added to enable NX3031 devices to properly
aggregate frames for LRO:
commit 6598b169b856793f8f9b80a3f3c5a48f5eaf40e3
Author: Dhananjay Phadke <dhananjay@...xen.com>
Date: Sun Jul 26 20:07:37 2009 +0000
netxen: enable ip addr hashing
This patch is a followup to that fix as it allows LRO aggregation on
bonded devices that contain an NX3031 device. This was tested on an
older distro and modified slightly to the latest upstream.
