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

[Francois Romieu <romieu@fr.zoreil.com>]

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: 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.
