[PATCH] WE-19 for kernel 2.6.13
Hi Jeff,
This is version 19 of the Wireless Extensions. It was supposed
to be the fallback of the WPA API changes, but people seem quite happy
about it (especially Jouni), so the patch is rather small.
The patch has been fully tested with 2.6.13 and various
wireless drivers, and is in its final version. Would you mind pushing
that into Linus's kernel so that the driver and the apps can take
advantage ot it ?
It includes :
o iwstat improvement (explicit dBm). This is the result of
long discussions with Dan Williams, the authors of
NetworkManager. Thanks to him for all the fruitful feedback.
o remove pointer from event stream. I was not totally sure if
this pointer was 32-64 bits clean, so I'd rather remove it and be at
peace with it.
o remove linux header from wireless.h. This has long been
requested by people writting user space apps, now it's done, and it
was not even painful.
o final deprecation of spy_offset. You did not like it, it's
now gone for good.
o Start deprecating dev->get_wireless_stats -> debloat netdev
o Add "check" version of event macros for ieee802.11
stack. Jiri Benc doesn't like the current macros, we aim to please ;-)
All those changes, except the last one, have been bit-roting on
my web pages for a while...
Patches for most kernel drivers will follow. Patches for the
Orinoco and the HostAP drivers have been sent to their respective
maintainers.
Have fun...
Jean
