Vendor Namespace Question

Vendor Namespace Question

[C. McPherson]

Hello all:
I was just trying to use the latest stable backports-3.18-rc1-1 and I 
noticed that there is no longer structure members in the 
ieee80211_rx_status structure for Vendor namespace information?  In my 
backports 3.14 version I used them to add some register information to 
the radiotap header in the lab. How does one use the vendor name space 
without those structure members?

Thanks for you assistance
Clyde

We removed this from the Linux kernel because there was no driver using
it and we needed the space for other purposes. That said, it shouldn't
be too difficult to put it back by keeping the OUI/subtype also in the
skb->data rather than the rx_status (which is now full enough to no
longer have space for it, I believe)

Thanks so much for the info Johannes. I did notice that rx_status was 
getting full.  I'll go ahead and put it in skb->data, that's a good idea.

I just sent a patch to restore vendor radiotap stuff in mac80211.

Works for me, and I might actually have a use case for it, but please
tell me if you have issues with it.
