This patch adds set-field operations for nd_target, nd_sll, and nd_tll fields,
with and without masks, using Nicira extensions and OpenFlow 1.2 protocol. Unit
tests are included.
This version performs all ND set-field processing in userspace. All ND
set-field functions pass functional testing, including ICMPv6 checksum
validation and regression test with IPv4/ARP traffic. Tests were performed on
CentOS 6.6, CentOS 7, and Ubuntu 14.04 LTS.
This version was developed against the master branch. (Thanks for the pointer,
Ben!)
