Re: [patch 1/5] d80211: remove bitfields from ieee80211_tx_control

[David Kimdon <david.kimdon@devicescape.com>]

I am not particularily attached to bitfields or no bitfields.  I am
interested in getting d80211 merged.  Bitfields have been discussed
as an important TODO.  Perhaps this can serve as a starting point for
discussion of the tasks to complete before d80211 is merged?

I agree that we end up with more characters in the file, the bitfield
syntax is more concise.  However, I don't find it 'much' harder to
read or maintain, it is a matter of taste.

Well at least as far as code size goes gcc 4.1.2 still produces
slightly larger code with the bitfields.
