Subject: [PATCH net-next v3 04/16] mctp: Add sockaddr_mctp to uapi
Date: Fri, 23 Jul 2021 16:29:20 +0800	[thread overview]
Message-ID: <20210723082932.3570396-5-jk@codeconstruct.com.au> (raw)
In-Reply-To: <20210723082932.3570396-1-jk@codeconstruct.com.au>

This change introduces the user-visible MCTP header, containing the
protocol-specific addressing definitions.

Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au>

v2:
 - include MCTP_ADDR_NULL and MCTP_TAG_* definitions
v3:
 - don't use GENMASK/BIT in uapi
