Updated Publication: "Networking with PCI adapters and functions"

Coinciding with the switch to the new Network Express adapters, we have updated our documentation to include the new card here.

 From the introduction:

Note that Network Express adapters now also support promiscuous mode as required by Open vSwitch in a KVM context!
