This was a stupid mistake, if you do it correctly it actually works and
so far has only triggered a single warning on my system:

[  217.507048] SKB BUG: Invalid truesize (4294964120) size=432, sizeof(sk_buff)=176

that was with my patch though to update skb->truesize during !skb->sk
pskb_expand_head() calls.

Thanks a lot for tracking this down Johannes.

No, no, I haven't. The only thing that was a stupid mistake was my
change to check the actual allocated skb size in the truesize bug rather
than do the < len check... That works, when you do it as in that patch,
but the mac80211 stuff still stands (along with all the questions I
posted elsewhere in this thread)
