[openib-general] [PATCH 04/10] IPoIB: Fix SA client retransmission strategy

[Roland Dreier]

From: Hal Rosenstock <halr at voltaire.com>

We got a little mixed up with what the backoff member holds in the
IPoIB multicast group structure: sometimes it was used as a number of
seconds, and sometimes it was used as a number of jiffies.  Fix the
code so that backoff is always in seconds.
