From 1ce8460496c05379c66edc178c3c55ca4e953044 Mon Sep 17 00:00:00 2001 From: Yotam Gigi Date: Wed, 1 Feb 2017 15:30:02 +0200 Subject: net: Introduce ife encapsulation module This module is responsible for the ife encapsulation protocol encode/decode logics. That module can: - ife_encode: encode skb and reserve space for the ife meta header - ife_decode: decode skb and extract the meta header size - ife_tlv_meta_encode - encodes one tlv entry into the reserved ife header space. - ife_tlv_meta_decode - decodes one tlv entry from the packet - ife_tlv_meta_next - advance to the next tlv Reviewed-by: Jiri Pirko Signed-off-by: Yotam Gigi Signed-off-by: Jamal Hadi Salim Signed-off-by: Roman Mashak Signed-off-by: David S.
