Thanks! I merged your stuff and pushed out an updated patch.

[PATCH] IP1000 Gigabit Ethernet device driver

This is a cleaned up fork of the IP1000A device driver:

http://www.icplus.com.tw/driver-pp-IP1000A.html

Open issues:

- ipg_probe() looks really fishy and doesn't handle all errors
(e.g. ioremap failing).
- ipg_nic_do_ioctl() is playing games with user-space pointer.
We should use ethtool ioctl instead as suggested by Arjan.
- something (PHY reset/auto negotiation?) takes 2-3 seconds and
appears to be done with interrupts disabled.

Changelog:

- Kill 2.2 and 2.4 compatability macros
- Use proper module API
- Use proper PCI API
- Use netdev_priv
- Consolidate headers to one file
- Use __iomem annotations
- Use iomap instead of read/out for I/O
- Remove obfuscating register access macros
- Remove changelogs
- Remove ether_crc_le() -- use crc32_le() instead.
- No more nonsense with root_dev -- ipg_remove() now works.
- Move PHY and MAC address initialization into the ipg_probe(). It was
previously filling in the MAC address on open which breaks some user
space.
- Folded ipg_nic_init into ipg_probe since it was broke otherwise.

I don't have the hardware, so I don't know if I broke anything.
The patch is 128 KB in size, so I am not including it in this
mail. You can find the patch here:
