I tried using the PKey since posting, but it alone did not solve the issue.

Turns out I was using the wrong port GUID (bad copy and paste) when testing with
ibping. It has been working all along.

I have just now solved the issue.

The partitions.conf file took me in the right direction.  The solution was to
use rate=2 instead of as rate=1 (which apparently is a reserved value).  I was
unable find documentation for the rate-value pairs, so I was assuming that
rate=1 was 2.5.  I finally found documentation for the rates in a post on the
old ofa-general mailing list:

#define IB_PATH_RECORD_RATE_2_5_GBS             2
#define IB_PATH_RECORD_RATE_10_GBS              3
#define IB_PATH_RECORD_RATE_30_GBS              4
#define IB_PATH_RECORD_RATE_5_GBS               5
#define IB_PATH_RECORD_RATE_20_GBS              6
#define IB_PATH_RECORD_RATE_40_GBS              7
#define IB_PATH_RECORD_RATE_60_GBS              8
#define IB_PATH_RECORD_RATE_80_GBS              9
#define IB_PATH_RECORD_RATE_120_GBS             10

#define IB_MIN_RATE    IB_PATH_RECORD_RATE_2_5_GBS
#define IB_MAX_RATE    IB_PATH_RECORD_RATE_120_GBS

Setting my partitions.conf as follows has solved the issue:

Default=0x7fff,ipoib,rate=2:ALL=full;

Thanks everyone for the help.
