[rriggio]

This patch add support for 11n frame injection across the entire click router.

• Import the reference radiotap parsing code
• Add a new SettXRateHT element that can set HT rate
• Add support for retry chains

Hi,

I have opened a separate pull request because I have deleted the forked used for the previous one (sorry for the confusion).

This patch could be the basis for a revamped wifi support in click. However, revising all the existing wifi elements would require some time and for sure more than 2 hands. If anybody out there could be interested in this activity please let me know. Click has been a precious tool in my work and I would be happy to give back a bit.

R.

The extern C wrapping should go in the header file, I think, as it does in click/md5.h and click/crc32.h, rather than in the including files
