Everyone:

I'm makinga server that makes and breaks a lot of connections using 
mpd. Unlike earlier versions of FreeBSD, 10.0 seems to react to 
every new link (which involves bringing up an "ng" 
pseudo-interface) by running the pccard_ether script. It also seems 
to try running dhclient on interfaces that don't use DHCP. I've 
never seen it this busy before, and all of this activity is for 
naught; the machine doesn't use DHCP and mpd manages all the 
logistics of bringing up an "ng" interface itself. Why the change 
and all of the useless activity?
