Subject: [PATH 2.6.33 2/3] net: Kconfig change for Micrel KSZ884X driver

From: Tristram Ha <Tristram.Ha@...rel.com>

Add Micrel KSZ8841/KSZ8842 PCI Ethernet chip support.

Some users like to use KSZ8842 switch to run Spanning Tree Protocol.  As a result a hardware STP support was implemented so that the host does not waste CPU time forwarding each and every packet.
