SVN rev 201654 on 2010-01-06 16:48:59Z by bz
MFC r184720:
Fix a bug introduced with r182851 (r201653 in stable/7) splitting
tcp_mss() into tcp_mss() and tcp_mss_update() so that tcp_mtudisc()
could re-use the same code.
In case we return early and got a metricptr to pass the hostcache
info back to the caller we need to initialize the data to a defined
state (zero it) as tcp_hc_get() would do if there was no hit.
Without that the caller would check on random stack garbage which
could lead to undefined results.
This only affected tcp_mss() if there was no routing entry for the peer,
tcp_mtudisc() was not affected.
