svn commit: r235255 - in head/sys/dev: dc fxp usb/net xl

[Marius Strobl]

Author: marius
Date: Fri May 11 02:40:40 2012
New Revision: 235255
URL: http://svn.freebsd.org/changeset/base/235255

Log:
  - Change the module order of these MAC drivers to be last so they are
    deterministically handled after the corresponding PHY drivers when
    loaded as modules. Otherwise, when these MAC/PHY driver pairs are
    compiled into a single module probing the PHY driver may fail. This
    makes r151438 and r226154 actually work. [1]
    Reported and tested by: yongari (fxp(4))
  - Use DEVMETHOD_END.
  - Use NULL instead of 0 for pointers.
