Subject: [PATCH iproute 3/5] ila: support to configure checksum neutral-map-auto
Date: Wed, 22 Nov 2017 12:05:35 -0800	[thread overview]
Message-ID: <20171122200537.26703-4-tom@quantonium.net> (raw)
In-Reply-To: <20171122200537.26703-1-tom@quantonium.net>

Configuration support in both ip ila and ip LWT for checksum
neutral-map-auto. This is a mode of ILA where checksum
neutral mapping is assumed for packets (there is no C-bit
in the identifier to indicate checksum neutral).

Signed-off-by: Tom Herbert <tom@quantonium.net>
