Subject: [PATCH 12/12]: wext: Emit event stream entries correctly when compat.

---

Three major portions to this change:

1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.

2) Delete iw_stream_check_add_*(), they are unused.

3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.

4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3.

With a lot of help and bug fixes from Masakazu Mokuno.

Here is a respin of patch 12 with the ps3 bits included, thank
for noticing Johannes.

I've also respun the tree on kernel.org so that it's
fixed there too.

wext: Emit event stream entries correctly when compat.

Three major portions to this change:

1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.

2) Delete iw_stream_check_add_*(), they are unused.

3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.

4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3.

With a lot of help and bug fixes from Masakazu Mokuno.

Likely yes, I guess that won't get hit with an allmodconfig
build on sparc64 :(

It would be really nice if we had some more compat layers
so that the ps3 bus probing layer just nopped out but you
could at least build test drivers on other platforms.

That wouldn't help, as it runs on top of an hypervisor API.

The wired part may be merged back with spider_net one day...

David,

What tree should be used for this patch? On wireless-testing that
git-describe lists as v2.6.26-rc4-8782-gd9a8bd7, hunk 5 for mlme.c fails.

I said in the 0/12 posting that the patches are based upon
net-next-2.6

Awesome stuff. With respect to wpa supplicant, I'd expect we need some
sort of handling for this wrt. notifications (multicast) which is a bit
awkward, but maybe wpa supplicant doesn't care too much.
