From ebf4e808fa0b22e551baf862e17c26c325c068f4 Mon Sep 17 00:00:00 2001 From: Ilya Lesokhin Date: Mon, 30 Apr 2018 10:16:12 +0300 Subject: net: Add Software fallback infrastructure for socket dependent offloads With socket dependent offloads we rely on the netdev to transform the transmitted packets before sending them to the wire. When a packet from an offloaded socket is rerouted to a different device we need to detect it and do the transformation in software.
