+ ---help---
+ This module provides glue between core networking code and device
+ drivers in order to support hardware switch chips in very generic
+ meaning of the word "switch". This include devices supporting L2/L3 but
+ also various flow offloading chips, including switches embedded into
+ SR-IOV NICs.
