commit f6d60848baf9f4015c76c665791875ed623cd5b7 Author: Ralph Campbell <ralph.campbell@qlogic.com> Date: Thu May 6 17:03:19 2010 -0700
IB/ipath: Remove support for QLogic PCIe QLE devices
The ib_qib driver is taking over support for QLogic PCIe QLE devices, so remove support for them from ib_ipath. The ib_ipath driver now supports only the obsolete QLogic Hyper-Transport IB host channel adapter (model QHT7140).

There you go. It's been HTX only since 2010, and those cards were already old then. I think we should seriously consider deprecating and then removing the driver.
