>Description:
ifconfig alias seems to overwrite default address.

/etc/rc.conf:
ifconfig_bge0="inet aaa.bbb.ccc.ddd  netmask 255.255.255.0"
ifconfig_bge0_alias0="inet aaa.bbb.ccc.eee  netmask 255.255.255.255"

ifconfig reports NO aaa.bbb.ccc.ddd.

when r227776M, ifconfig alias work correctly.

>How-To-Repeat:
ifconfig bge0 inet aaa.bbb.ccc.ddd/24
ifconfig bge0 inet aaa.bbb.ccc.eee/32 alias

ifconfig
