From: Jiri Kosina <jkosina@...e.cz>

PCI: nVidia's MCP61 ethernet card needs quirk for wrong class

The MCP61 ethernet controller from nVidia (NVENET_19) contains wrong
PCI class:

	00:07.0 Bridge [0680]: nVidia Corporation MCP61 Ethernet [10de:03ef] (rev a2)

i.e. it identifies itself as a bridge. Fix this.
