ae 5a416ec2ac Relax requirement to packet size of CARP protocol and remove version check.
CARP shares protocol number 112 with VRRP (RFC 5798). And the size of
VRRP packet may be smaller than CARP. ipfw_chk() does m_pullup() to at
least sizeof(struct carp_header) and can fail when packet is VRRP. This
leads to packet drop and message about failed pullup attempt.
Also, RFC 5798 defines version 3 of VRRP protocol, this version number
also unsupported by CARP and such check leads to packet drop.

carp_input() does its own checks for protocol version and packet size,
so we can remove these checks to be able pass VRRP packets.
