Subject: [PATCH 3/3] proto: fix byteorder of ETH_P_* values
Date: Tue, 19 Aug 2014 00:27:31 +0100	[thread overview]
Message-ID: <1408404451-9075-4-git-send-email-kaber@trash.net> (raw)
In-Reply-To: <1408404451-9075-1-git-send-email-kaber@trash.net>

The ethernet header type is in big endian byte order, the ETH_P_* values
are in host byte order however. Fix this using __constant_htons().
