freebsd/etc/pccard_ether
Ceri Davies f5c4146d5a The submitter of bin/75786 turned out to not have removable interfaces,
and so the fix committed in r1.42 was not quite correct for the case
where there are two or more DHCP consuming removable interfaces - dhclient
must be restarted so that the other interfaces continue to function
correctly.
