Hello,

Are following true?
When manually load/reload hostapd, works
When loaded by rc.conf, doesn't work

If so, please try attached patch. (patch to if_run.c only) Or, here is a patched file.
http://gitorious.org/run/run/blobs/raw/cmdq_fix/dev/usb/wlan/if_run.c

When auto-loading, the driver is brought up and down a few times. It might be the cause. So, when you test, please reboot rspro and let rc.conf handle init process rather than manually start driver/hostapd. And
#arp -d -a
on rspro, freebsd laptop. and macbook would help for testing. (If it works on mac) So, that clients have to send arp request. If macbook receives "who-has 192.168.1.50" arp request packets, it should work. If macbook supports
# tcpdump -vv -xxx -i wlan0 'arp'
and see if macbook gets this.
