Subject: Inform user land when vltime / pltime changes.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=6859a790d2a42c75c91ed09f7e624578bf78b567;p=openbsd

Inform user land when vltime / pltime changes.

Do not send a RTM_CHGADDRATTR route message when the address is
tentative because we will send one when DAD finishes.

To be used by rad(8) shortly.

OK bluhm
