It is attached in this message. Again it's against a very recent 9-STABLE, I still haven't found time to see if it applies to CURRENT. It does allow you to do crazy stuff like ipv6_addrs_re0="2001:db8:1111:2222::1-ffff/64" However I didn't find anything to limit the number of aliases in the ipv4 version of the function either. Please test it :) Then a question about the PR (http://www.freebsd.org/cgi/query-pr.cgi?pr=174225) I wrote, how can I attach this new patch to it? The submit follow up -button fires up my email client and I'm not so sure how to submit a new patch for the PR in an email in such a way that it appears properly formatted in the PR.
