The only driver that shows this problem is r8712u. One thought that I just had
is that this driver does not use mac80211, which is why it is in staging.
Instead it uses a Realtek soft MAC layer derived from the obsolete softmac
driver that was in the kernel in the 2.6.20 time frame. That means that none of
the skbs have ever been cloned by any part of the wireless code.
