3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nithin Sujir <nsujir@xxxxxxxxxxxx>
commit 375679104ab3ccfd18dcbd7ba503734fb9a2c63a upstream.
The current driver assumes that an skb fragment can only be upto jumbo
size. Presumably this was a fast-path optimization. This assumption is
no longer true as fragments can be upto 32k.
v2: Remove unnecessary parantheses per Eric Dumazet.
