Hi,

        I've just read davem's post at netdev about the brokeness of
referencing skbs after passing it to netif_rx, so please consider applying
this patch. Ah, this was just added to the Janitor's TODO list at
http://bazar.conectiva.com.br/~acme/TODO and I'm doing a quick audit in the
net drivers searching for this, maybe some more patches will follow.
