Subject: [PATCH][v3][16/21] IPoIB IPv6 support
Date: Mon, 13 Dec 2004 10:09:46 -0800 [thread overview]
Message-ID: <20041213109.iziHvQZqtmP83gmx@topspin.com> (raw)
In-Reply-To: <20041213109.5NKezuGE9PMejMSM@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-07.txt
