Re: [PATCH 2/2] ipg: redundancy with mii.h

Btw the whole serie is available in branch 'netdev-ipg' at:
git://electric-eye.fr.zoreil.com/home/romieu/linux-2.6.git

The interim steps may be useful if testing reveals something wrong
(especially if it happens in a few weeks/months).

ipg: sanitize the pci device table

- vendor id belong to include/linux/pci_id.h ;
- the pci table does not include all the devices in nics_supported ;
- qualify the pci table as __devinitdata ;
- kill 50 LOC.

ipg: plug leaks in the error path of ipg_nic_open

Added ipg_{rx/tx}_clear() to factor out some code.

ipg: leaks in ipg_probe

The error paths are badly broken.

Bonus:
- remove duplicate initialization of sp;
- remove useless NULL initialization of dev;
- USE_IO_OPS is not used (and the driver does not seem to care about
posted writes, rejoice).

ipg: speed-up access to the PHY registers

Reduce delays when reading/writing the PHY registers so we clock the
MII management interface at 2.5 MHz (the maximum according to the
datasheet) instead of 500 Hz.

ipg: root_dev removal and PHY initialization

- 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.

ipg: initial inclusion of IC Plus IP1000 driver

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

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

Open issues include but are not limited to:

- 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.
- For multiple devices, the driver uses a global root_dev and
ipg_remove() play some tricks which look fishy.
