From a9e527e3f9f4510e9f3450ca3bc51bc3ef2854fd Mon Sep 17 00:00:00 2001 From: Rolf Manderscheid Date: Mon, 10 Dec 2007 13:38:41 -0700 Subject: IPoIB: improve IPv4/IPv6 to IB mcast mapping functions An IPoIB subnet on an IB fabric that spans multiple IB subnets can't use link-local scope in multicast GIDs. The existing routines that map IP/IPv6 multicast addresses into IB link-level addresses hard-code the scope to link-local, and they also leave the partition key field uninitialised. This patch adds a parameter (the link-level broadcast address) to the mapping routines, allowing them to initialise both the scope and the P_Key appropriately, and fixes up the call sites. The next step will be to add a way to configure the scope for an IPoIB interface.
