Hi there,

how did you get hostapd to compile against libnl-1.1? As far as I tried, it
did not compile. Working with latest git version of rt2x00, hostapd and libnl
at least brought up the interface, though I ran into other problems (see my
previous post "hostapd git with rt73usb not working")

Kind regards,
Lee
