Subject: wperf - a test tool for monitor mode frame injection/reception on mac80211

Hi,

I am working on improving the monitor mode frame injection/reception
functionality in mac80211. For this purpose I have written a small
test tool that can transmit and receive frames in monitor mode. It can
be used to measure throughput and packet loss for Tx and Rx, in AP or
STA mode, with or without encryption.

The source code is on GitHub, https://github.com/anyfi/wperf. There
are also statically-linked binaries for mips and x86:

To transmit frames in monitor mode from an AP:

1) Set up an wireless network in AP mode with mac80211 and hostapd,
and create a monitor interface on the phy

2) Connect a STA to the wireless network

3) Run a wperf UDP server on the STA

    wperf -s

4) Run a wperf client in monitor mode on the AP

    wperf -c <STA IP> --monitor=<monitor ifname> --bssid=<AP BSSID>
--dhost=<STA MAC>
