From 4d288d5767f853bfca25adc7b6030dc95518cb2e Mon Sep 17 00:00:00 2001 From: Yi Zou Date: Fri, 27 Feb 2009 14:06:59 -0800 Subject: [PATCH] [SCSI] net: add FCoE offload support through net_device This adds support to provide Fiber Channel over Ethernet (FCoE) offload through net_device's net_device_ops struct. The offload through net_device for FCoE is enabled in kernel as built-in or module driver.
