Subject: [PATCH][v4][18/24] IPoIB IPv6 support
Date: Sun, 19 Dec 2004 22:15:14 -0800 [thread overview]
Message-ID: <200412192215.69tnzAhGIT1vQGLF@topspin.com> (raw)
In-Reply-To: <200412192215.vegmgBmv5xungHlQ@topspin.com>
Add ipv6_ib_mc_map() to convert IPv6 multicast addresses to IPoIB
hardware addresses, and add support for autoconfiguration for devices
with type ARPHRD_INFINIBAND.
The mapping for multicast addresses is described in
http://www.ietf.org/internet-drafts/draft-ietf-ipoib-ip-over-infiniband-08.txt
