>Description:
network configuration utilities, namely 'ifconfig' and 'dhclient' fail
when accessing qe* interfaces on qec (Quad Ethernet Controller) with
Invalid argument.

Device enumeration from 'dmesg':

>How-To-Repeat:
On SPARCstation equipped with qec/qe interfaces, install NetBSD-6.0_BETA2
and attempt to configure one of the qe* interfaces with 'ifconfig' or
'dhclient'.

May also affect "be*" interfaces on qec base board, but this is
untested.

These worked fine in all Netbsd up to 5.1_STABLE...
