From faec2f7b96b555055d0aa6cc6b83a537270bed52 Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Thu, 15 Feb 2007 17:00:17 -0800 Subject: IB/sa: Track multicast join/leave requests The IB SA tracks multicast join/leave requests on a per port basis and does not do any reference counting: if two users of the same port join the same group, and one leaves that group, then the SA will remove the port from the group even though there is one user who wants to stay a member left. Therefore, in order to support multiple users of the same multicast group from the same port, we need to perform reference counting locally. To do this, add an multicast submodule to ib_sa to perform reference counting of multicast join/leave operations. Modify ib_ipoib (the only in-kernel user of multicast) to use the new interface.
