[openib-general] [PATCH 1 of 3] core: static rate encoding change support

[Jack Morgenstein]

For static rate encoding, use encoding rate field from PathRecord,
with addition of value 0, for backwards compatibility with
current usage.

Push translation of static rate to hca format to provider layer,
where it belongs.
