Supposedly, according to what I've read in if_sppsubr.c, pppoe interfaces
are supposed to send LCP keepalives every 10 seconds, but every once in
awhile (actually, its very common), the keepalive's aren't sent for up to
15 minutes.  I'm watching the kernel messages from "ifconfig pppoe0
debug" and also the output of a "tcpdump -i pppoe0 not ip".  The end
result of this is that dead connections aren't detected for some time.

Is anybody else seeing this?  Could this bug be related to the callout
wheel corruption described in PR 20390?
