Michael Brown b0e236a9ee [netdevice] Process all received packets in net_poll() The current logic is to process at most one received packet per call to net_poll(), on the basis that refilling the hardware descriptor ring should be delayed as little as possible. However, this limits the rate at which packets can be processed and ultimately ends up adding latency which, in turn, limits the achievable throughput. With temporary modifications in place to essentially remove all resource constraints (heap size increased to 16MB, RX descriptor ring increased to 64 descriptors) and a TCP window size of 1MB, the throughput on a gigabit (i.e. 119MBps) network can be observed to fall off exponentially from around 115MBps to around 75MBps. Changing net_poll() to process all received packets results in a steady 119MBps throughput. Signed-off-by: Michael Brown <mcb30@ipxe.org>		12 anos atrás
