hello,
currently we allow users to create a vlan and a bridge on the same
interface, like this:
% ifconfig ix0.100 create
% ifconfig bridge0 create addm ix0
i am aware that some people are using this in production, but because it
doesn't work properly[0], i would like to forbid this configuratio

hello,
i have proposed a patch to merge traceroute6 into traceroute, so that
traceroute supports both IPv4 and IPv6 addresses:
https://github.com/freebsd/freebsd-src/pull/1647
jlduran@ has proposed an alternative approach to achieve the same thing
which is mentioned in the PR comments.

hello,
over the last few days i have been doing a bit of work on VLAN filtering
for bridge(4), which i thought i'd mention here in case anyone is
interested. the purpose of this is to extend the existing bridge VLAN
support to make it more generally useful.
