ps3: gigabit ethernet driver for PS3, take3
Hi,
This is the third submission of the network driver for PS3.
The differences from the previous one are:
- renamed source file names so that their prefix can match
with the module name
- added cbe-oss-dev@ozlabs.org line for MAINTAINER file
- changed some in copyright comments
If there are no more comments, please apply for 2.6.23.
Thank you

Subject: PS3: Ethernet driver
From: Masakazu Mokuno <mokuno@sm.sony.co.jp>
