[Info]d80211 : Understanding d80211

[Udayan Singh]

Hi,

I wanted to understand the code of d80211 (thanks to James Ketrenos
for the info he provided) and also work in it.

I found that I can get the latest patches regarding the same from :

http://www.kernel.org/pub/linux/kernel/people/linville/wireless-2.6/

Also, in the main kernel tree the development for 802.11 is in
"drivers/net/wireless/*" .

Well, I did not find any reference of d80211 in lk 2.6.18.1, though a
few places I read that the possible merger would be in lk 2.6.19. I
hope I got it right ?

Any docs that I can read through that you would recommend from where I
can start up ?

Is there any place where I can download the code in a similar pattern
as we do from kernel.org for the mainstream kernel ?

Wireless-2.6 contains the developmental version of wireless code _NOT_ using d80211. The d80211 
development version is at git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-dev.git 
and must be downloaded with git, not ftp or http.

The d80211 drivers are in drivers/net/wireless/d80211/*. The drivers in drivers/net/wireless/* do 
not use d80211.

The merger of d80211 with mainline kernel will occur with 2.6.21 or later. At the moment, there are 
several reasons for it not to be included in the mainline kernel. The stable kernels (2.6.18.X and 
earlier), and the mainline developmental kernel (2.6.19-rcX) do not include the d80211 code.

Only the code AFAIK.

See the previous git reference.

referring to the standards might  be good i.e. 802.11 standards ??

I intend to work in the manner:

1. There are quite many standards that have already been implemented
e.g. 802.11a/b/g in the kernel (here wireless-dev). If there is a new
standard wrt. 802.11x coming in, then I can work on same.

2. Work on an already implemented standard and try to add a missing
feaature into it.

Kindly let me know your opinions.
