ps3: gigabit ethernet driver for PS3, take3

Browse source 
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>
