Updated the patch, URL remains the same:
  http://codelabs.ru/fbsd/carp-ouibase.diff

Changes:

 - full MAC is settable via ether/lladdr/link keyword, no
   ouibase keyword now exists;

 - these keywords accept "carp" and "vrrp" keywords making
   them to set new and old bases with the last octet set to
   the VHID;

 - network.subr was updated not to mess with any keywords that
   go after 'vhid' and just pass it down to ifconfig as is.

I did two days of testing and hadn't yet found any problems.
