[Steve Wise]

Vlad,

Please pull this patch from

git://www.openfabrics.org/~swise/ofed-1.3 ofed_kernel

This has been accepted upstream and is needed for ofed-1.3 to support 
new device types.

Thanks,

Steve.

RDMA/cxgb3: Fix the T3A workaround checks.

Correctly work around T3A issues by checking "hwtype != T3A" instead of
"hwtype == T3B".  Needed for new hw types.
