Hello Johannes,
in response to one of your brcm80211 review comments, I am trying to
replace functions that calculate frame duration with Mac80211 counterparts.
As such, I have a hard time grasping this function:
http://lxr.free-electrons.com/source/net/mac80211/util.c#L108
A couple of questions:
a. The comment in the 'else' branch does not mention 802.11n, but I
think it should. Agree ?
b. The long/short preamble choice applies to CCK rates only. But this
function does not take that into account. Is that on purpose ?
c. In 802.11n there are 4 preamble types possible:
- long (CCK rates)
- short (CCK rates)
- green field
- mixed mode
The function does not seem to take the last two types into account.
Should it ?
Bye, Roland.
