From 2d9b33c0fd7d812a7296cd71f14c03925f815f28 Mon Sep 17 00:00:00 2001 From: Ghanan Gowripalan Date: Thu, 9 Sep 2021 12:31:53 -0700 Subject: Remove link/packetsocket This change removes NetworkDispatcher.DeliverOutboundPacket. Since all packet writes go through the NIC (the only NetworkDispatcher), we can deliver outgoing packets to interested packet endpoints before writing the packet to the link endpoint as the stack expects that all packets that get delivered to a link endpoint are transmitted on the wire. That is, link endpoints no longer need to let the stack know when it writes a packet as the stack already knows about the packet it writes through a link endpoint.
