Hey all,
I recently purchased a Netgear WG111v2 (based on rtl8187b) and after
seeing scattered reports[1] that master mode may be supported by the
rtl8187 driver. Unfortunately, hostapd throws up when it attempts to put
the card into master mode. Is master mode supported by this driver? I've
tried both 2.6.34 as well as the latest wireless-testing tree and
neither seem to work.
I noticed there was a patch[2] sent out a few years back, but it seems
no one followed up. While I don't have much experience working with
wireless hardware I've done kernel driver work before, so with some
guidance I might be able to finish up that patch. Any input would be
greatly appreciated. Thanks!

My WG111V2 has an RTL8187L chip in it, not an RTL8187B. No, master mode is NOT
supported by this driver. Adding that feature has been on my list of things to
do, but the priority is very low. I really have little desire to convert my $600
laptop into a $40 access point.

That patch is useless. The rtl8187 driver and mac80211 have changed so much that
it cannot be made to apply, and would not be likely to work.
One other thing to consider. The RTL8187L has only a single transmit queue. Will
the device be able to transmit beacons with an appropriate timing accuracy?
To modify the driver, you will need to study some other driver that does work in
master mode.

There were some discussion a while back that some generic master mode
support for all mac80211-based drivers might eventually happen. Is
that still the case?

I've followed the driver of the rtl818x in 26.34 and draw some
pictures of source.However, some additional work interrupted me.
