+	This is a low-level driver for PathScale InfiniPath host channel
+	adapters (HCAs) based on the HT-400 and PE-800 chips.

+config INFINIBAND_IPATH

+	---help---
+	This is a driver that provides InfiniBand verbs support for
+	PathScale InfiniPath host channel adapters (HCAs).  This
+	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).
