From 76564261a7db80c5f5c624e0122a28787f266bdf Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Mon, 13 Jan 2020 23:31:40 +0100 Subject: net: macsec: introduce the macsec_context structure This patch introduces the macsec_context structure. It will be used in the kernel to exchange information between the common MACsec implementation (macsec.c) and the MACsec hardware offloading implementations. This structure contains pointers to MACsec specific structures which contain the actual MACsec configuration, and to the underlying device (phydev for now).
