better error messages if the user tries to use symbolic names such
as "echo" and "echorep" in "ipv6-icmp ... icmp-type ..." rules.
Consider the following rules:
# cat /etc/ipf6.conf
pass in quick proto ipv6-icmp from any to any icmp-type 128
pass in quick proto ipv6-icmp from any to any icmp-type echo
Use of symbolic names give now the following error:
# ipf -Fa -6f /etc/ipf6.conf
2: Unknown ICMPv6 type (echo) specified (use numeric value instead)
The first rule with numeric value will work as expected:
# ipfstat -6hi
0 pass in quick proto ipv6-icmp from any to any icmp-type 128
NOTE: You MUST use numerical values for ICMPv6 types. See
/sys/netinet/icmp6.h for available codes!
ROOT localhost:~> /etc/rc.d/ipfilter reload

22: Invalid icmp-type (echo) specified
With version 1.7 everything works just fine:
ROOT localhost:~> /etc/rc.d/ipfilter reload
Reloading ipfilter rules.

this fix ipfstat reported:
0 pass in quick proto ipv6-icmp from any to any
while after this fix:
0 pass in quick proto ipv6-icmp from any to any icmp-type 8
This was just a display bug, the rule worked as expected.
