Date: Mon, 6 Jan 2014 14:37:24 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Nithin Nayak Sujir <nsujir@...adcom.com>, Michael Chan <mchan@...adcom.com>, "David S. Miller" <davem@...emloft.net> Subject: [PATCH 3.12 083/144] tg3: Expand 4g_overflow_test workaround to skb fragments of any size. 3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Nithin Sujir <nsujir@...adcom.com> 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.
