Could this perhaps fix the long outstanding bug (which appears to be
alignment related) when using ipfilter with the ea/eb drivers. An example
(IIRC) was:

block in all
pass in from 192.168.1.0/24 to any
pass out all

This would block all inward traffic from the 192.168.1.0/24 network
(IP address was 192.168.1.1 netmask 255.255.255.0). However,
"pass in from 192.168.0.0/16 to any" worked OK. Further experimentation
showed that a netmask > 18 bits blocked inward traffic even if the the
rule should pass it.
