As a matter of fact, the issue appeared in 6-STABLE on Jul 24 and
is still there.  Now devd(8) will invoke "/etc/pccard_ether stop"
when any network interface is destroyed.  In turn, pccard_ether
will flush all -inet routes if the rc.conf(5) variable removable_route_flush
is set to YES, which is its default setting.  Previously, this
scenario would take place only when an Ethernet interface was destroyed.
The question is:  Do all the routes really need to be flushed upon
the destruction of an interface?

Any ideas?
