2019-10-22netstack/tcp: software segmentation offloadAndrei Vagin
Right now, we send each tcp packet separately, we call one system call per-packet. This patch allows to generate multiple tcp packets and send them by sendmmsg. The arguable part of this CL is a way how to handle multiple headers. This CL adds the next field to the Prepandable buffer.

The blockingpoll_unsafe.go was copied to blockingpoll_noyield_unsafe.go during merging commit 7206202bb9439499. If it still stay here, it would cause build errors on non-amd64 platform.
