From 359ebda25aa06fe3a1d028f7e338a849165e661b Mon Sep 17 00:00:00 2001 From: Shmulik Ladkani Date: Mon, 18 Jul 2016 14:49:33 +0300 Subject: net/ipv4: Introduce IPSKB_FRAG_SEGS bit to inet_skb_parm.flags This flag indicates whether fragmentation of segments is allowed. Formerly this policy was hardcoded according to IPSKB_FORWARDED (set by either ip_forward or ipmr_forward).
