Date: Mon, 13 Dec 2010 00:46:23 +0100 (CET) From: Andi Kleen <andi@...stfloor.org> To: bhutchings@...arflare.com, davem@...emloft.net, gregkh@...e.de, ak@...ux.intel.com, linux-kernel@...r.kernel.org, stable@...nel.org Subject: [PATCH] [84/223] net: NETIF_F_HW_CSUM does not imply FCoE CRC offload 2.6.35-longterm review patch. If anyone has any objections, please let me know. ------------------ From: Ben Hutchings <bhutchings@...arflare.com> commit 66c68bcc489fadd4f5e8839e966e3a366e50d1d5 upstream. NETIF_F_HW_CSUM indicates the ability to update an TCP/IP-style 16-bit checksum with the checksum of an arbitrary part of the packet data, whereas the FCoE CRC is something entirely different.
