to complete that task.

-	tristate "QLogic HTX HCA support"
-	depends on 64BIT && NET && HT_IRQ
-	---help---
-	This is a driver for the deprecated 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.
-
-	If you have this hardware you will need to boot with PAT disabled
-	on your x86-64 systems, use the nopat kernel parameter.
-
-	Note that this driver will soon be removed entirely from the kernel.
