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. |
