Subject: [PATCH] IP1000A: IC Plus update 2006-08-22
Dear All:
I had regenerate this patch from:
git://git.kernel.org/pub/scm/linux/kernel/git/penberg/netdev-ipg-2.6.git
And, submit those modifications as one patch.
Add: "Remove and add some whitespace"
From: Jesse Huang <jesse@...lus.com.tw>
Change Logs:
- update maintainer information
- remove some default phy params
- remove threshold config from ipg_io_config
- ip1000 ipg_config_autoneg rewrite
- modify coding style of ipg_config_autoneg
- Add IPG_AC_FIFO flag when Tx reset
- For compatible at PCI 66MHz issue
- Remove and add some whitespace
