Navdeep Parhar e682d02e12 Support for TCP DDP (Direct Data Placement) in the T4 TOE module. ... Basically, this is automatic rx zero copy when feasible. TCP payload is DMA'd directly into the userspace buffer described by the uio submitted in soreceive by an application. - Works with sockets that are being handled by the TCP offload engine of a T4 chip (you need t4_tom.ko module loaded after cxgbe, and an "ifconfig +toe" on the cxgbe interface). - Does not require any modification to the application. - Not enabled by default. Use hw.t4nex.<X>.toe.ddp="1" to enable it.		2012-08-17 00:49:29 +00:00
