In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is a driver for the obsolete QLogic Hyper-Transport
IB host channel adapter (model QHT7140),
including InfiniBand verbs support. This driver allows these
devices to be used with both kernel upper level protocols such
as IP-over-InfiniBand as well as with userspace applications
(in conjunction with InfiniBand userspace access).
For QLogic PCIe QLE based cards, use the QIB driver instead.
