regression w/latest dhcpcd?

["John D. Baker" <jdbaker%consolidated.net@localhost>]

Following the recent pull-up of the latest 'dhcpcd' to netbsd-8, I updated,
build a release, and updated my NAT router.

Since then, I lose network connectivity after a few hours.

'dhcpcd' seems to log very little but I have "/etc/dhcpcd.exit-hook" log
the "REASON" every time it is called.

It appears that after a few hours 'dhcpcd' stops RENEWing the lease so
it expires, leaving the IP address and default route in place.  This
creates a "no route to host" condition as (apparently) the ISP's upstream
router is no-longer accepting packets from me.

I can recover by logging into the router and issuing:

  # dhcpcd -N <ext_if>


Anyone else having trouble like this?
