Jordan Whited f0230ce0b5 go.mod,net/tstun,wgengine/netstack: implement gVisor TCP GRO for Linux (#12921) ... This commit implements TCP GRO for packets being written to gVisor on Linux. Windows support will follow later. The wireguard-go dependency is updated in order to make use of newly exported IP checksum functions. gVisor is updated in order to make use of newly exported stack.PacketBuffer GRO logic. TCP throughput towards gVisor, i.e. TUN write direction, is dramatically improved as a result of this commit. Benchmarks show substantial improvement, sometimes as high as 2x. High bandwidth-delay product paths remain receive window limited, bottlenecked by gVisor's default TCP receive socket buffer size. This will be addressed in a follow-on commit. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them. The first result is from commit 57856fc without TCP GRO. Starting Test: protocol: TCP, 1 streams, 131072 byte blocks - - - - - - - - - - - - - - - - - - - - - - - - - Test Complete.
