2020-06-24	Add support for Stack level options.	Bhasker Hariharan
	Linux controls socket send/receive buffers using a few sysctl variables - net.core.rmem_default - net.core.rmem_max - net.core.wmem_max - net.core.wmem_default - net.ipv4.tcp_rmem - net.ipv4.tcp_wmem The first 4 control the default socket buffer sizes for all sockets raw/packet/tcp/udp and also the maximum permitted socket buffer that can be specified in setsockopt(SOL_SOCKET, SO_(RCV\|SND)BUF,...). The last two control the TCP auto-tuning limits and override the default specified in rmem_default/wmem_default as well as the max limits. Netstack today only implements tcp_rmem/tcp_wmem and incorrectly uses it to limit the maximum size in setsockopt() as well as uses it for raw/udp sockets. This changelist introduces the other 4 and updates the udp/raw sockets to use the newly introduced variables. The values for min/max match the current tcp_rmem/wmem values and the default value buffers for UDP/RAW sockets is updated to match the linux value of 212KiB up from the really low current value of 32 KiB.

	Updates #231 PiperOrigin-RevId: 309323808
2020-02-06	Make gonet consistent both internally and with the net package.	Ian Gudger
	The types gonet.Conn and gonet.PacketConn were confusingly named as both implemented net.Conn. Further, gonet.Conn was perhaps unexpectedly TCP-specific (net.Conn is not). This change renames them to gonet.TCPConn and gonet.UDPConn. Renames gonet.NewListener to gonet.ListenTCP and adds a new gonet.NewTCPListner function to be consistent with both the gonet.DialXxx and gonet.NewXxxConn functions as well as net.ListenTCP.

2020-01-15	Bump SO_SNDBUF for fdbased endpoint used by runsc.	Bhasker Hariharan
	Updates #231 PiperOrigin-RevId: 289897881
2020-01-14	Changes TCP packet dispatch to use a pool of goroutines.	Bhasker Hariharan
	All inbound segments for connections in ESTABLISHED state are delivered to the endpoint's queue but for every segment delivered we also queue the endpoint for processing to a selected processor. This ensures that when there are a large number of connections in ESTABLISHED state the inbound packets are all handled by a small number of goroutines and significantly reduces the amount of work the goscheduler has to perform. We let connections in other states follow the current path where the endpoint's goroutine directly handles the segments. Updates #231 PiperOrigin-RevId: 289728325
2020-01-13	benchmarks/tcp: set a number of channels to GOMAXPROCS	Andrei Vagin
	Updates #231 PiperOrigin-RevId: 289502669
2019-12-02	Import benchmark-tools to main repository.	Zach Koopmans
	This has adapted for use with bazel from the original commit a26e93769ebefd82593a43e22fb13a09717cfa6d. In particular, the style has been made consistent with internal python style guidelines, and the packages (including the main entrypoint) have been refactored in order to allow bazel testing targets.
