Subject: [net-next PATCH 2/2] add enic iovnl ops for dynamic vnics

From: Scott Feldman <scofeldm@...co.com>

Add enic iovnl ops to support setting port-profile for dynamic vnics.  Enic
dynamic vnics are just like normal enic eth vnics except dynamic vnics require
an extra configuration step to assign a port-profile identifier to the
interface before the interface is useable. Once assigned, link comes up
on the interface and is ready for I/O.  The port-profile is used to configure
the network port assigned to the interface.  The network port configuration
includes VLAN membership, QoS policies, and port security settings typical
of a data center network.
