m11:
Monitor 802.11 network interface. At yourself, you can call her
"shi yi mei" as chinese. Only for capturing all 802.11 radiotap
PF_PACKET:SOCK_RAW from a monitor interface, packets save as *.pcap.

Some m11's characters:
1. She is concise and elegant for easy use.
2. She is single-minded with linux and .pcap.
3. She is simple and nice to get along with, and you can KISS and
   unstand her with least effort.
4. She is a lovely girly, in a word.
5. She is not tcpdump that's a big miscellaneous man.
6. She can be cross-compiled to several archs like ARM, MIPS etc, cause
   she has a pure heart filled with only standard C and POSIX libs.

Usage:
  m11 [-i<ifname>] [-B<buffer size>] [-o<savefile.pcap>]
options:
  -h = show this help text
  -i = interface name like wlan0, moni0 etc.
  -B = buffer size KB to store all packets captured
  -o = output to file must like *.pcap
  -v = show version
example:
  ifconfig wlan0 down
  iw dev wlan0 set type monitor
  ifconfig wlan0 up
  m11 -i wlan0 -B 2048 -o tmp.pcap
  press CTRL+C to finish and store packets in tmp.pcap

Install:
make
make install

History:
2015-07-22
  m11 1st version v0.1
  m11 will be CRAZY if you take it with interface eth0 that is not
  802.11 monitor interface.
  Now, m11 has been tested with wifi module rtl8188cus driven by rtlwifi
  open source driver under Ubuntu 14.04.02-64bit with kernel 3.13.0.

2015-07-23
  m11 2nd version v0.2
  m11 will be CRAZY if stay with eth0 as before.
  Now, m11 always wait on the interface even if no data
  comes up, until we get packets when the interace is
  up halfway. So, the only way to end up capturing is
  to press CTRL+C.
change log:
  1. fix bug that terminal is blocked all the time
  2. assure that all packets are written to file when program exits
  3. prompt number of packets received
