From 613fa3ca9e9e6af57927dab238121010c510fe4c Mon Sep 17 00:00:00 2001 From: David Lebrun Date: Tue, 8 Nov 2016 14:59:20 +0100 Subject: ipv6: add source address argument for ipv6_push_nfrag_opts This patch prepares for insertion of SRH through setsockopt(). The new source address argument is used when an HMAC field is present in the SRH, which must be filled. The HMAC signature process requires the source address as input text.
