radiotap: add support for fixed order Tx flag

[vanhoefm]

This patch is part of my proposal to add a new bit to the Tx flags of the radiotap header. I consider the patch itself ready, but the code should only be merged if/once this addition has gone through radiotap's standardization process.

These flags are now standardized, so the updated ORDER flag can be merged as well. Context: https://lore.kernel.org/radiotap/3a082d1643fc5980ab1f11acda7e855c3eed60c7.camel@sipsolutions.net/T/#t

I'm surprised the TX field page wasn't updated: https://www.radiotap.org/fields/TX%20flags.html

The page on radiotap.org will be updated soon: https://lore.kernel.org/radiotap/3a082d1643fc5980ab1f11acda7e855c3eed60c7.camel@sipsolutions.net/T/#t
