Adds a set of traits representing features that hardware networking interface controllers expose. A number of source documents were used to come up with these traits: https://review.openstack.org/#/c/341341/4/specs/newton/approved/standardize-network-capabilities.rst https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Performance_Tuning_Guide/network-nic-offloads.html https://www.kernel.org/doc/Documentation/networking/scaling.txt https://www.kernel.org/doc/Documentation/networking/multiqueue.txt Change-Id: If8a9f08b8b45ebcac53ea9a406c210605b163516
