From bf6a9e31cfa768ce0a8e18474b3ca808641d9243 Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Mon, 10 Apr 2006 09:43:47 -0700 Subject: IB: simplify static rate encoding Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR.
