This is set of revised patches for adding offload support of Fiber Channel over Ethernet (FCoE) offload support through net_device for the Open-FCoE project maintained at http://www.open-fcoe.org. The original submission can be found at: http://marc.info/?l=linux-scsi&m=123507707821705&w=2 The included patches would add FCoE offload support through the net_device struct as shown in the series of patches followed here. This is achieved by adding nedev feature flags for FCoE FC CRC offload and large send offload through gso. The large receive offload by direct data placement (ddp) is achieved by the two function pointers to net_device_ops, to setup and release ddp context, ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done. One data member is added to net_device strut, namely fcoe_ddp_xid, which inidates the maximum exchange id allowed by LLD to perform ddp on the read I/O request. As the following patches touch both netdev and libfc/fcoe, and they are applicable to the current tip at www.open-fcoe.org w/ patches available at: http://marc.info/?l=linux-scsi&m=123576089125544&w=2 If they look alright, I will rework them later to be directly applicable to net-next, where the aforementioned fcoe/libfc fix patches are expected to be in kernel already through scsi-fixes.
