David,

That staging driver is expected to be deleted in a commit to be submitted in 
about one week. The new one will be in the regular wireless tree. The staging 
version was submitted so that there would be a driver in 3.14.

I was surprised to see this patch in John's list. It should have gone through 
GregKH. In fact, has has been suppressing all cleanups because the better one 
will be available soon.

I suggest that you drop this one now. I will, however, check the new source to 
make sure that the skb length is checked.

Thanks,

Larry
