This series adds support for steering of IPv6 receive flows.

Changes since v1:
* Fixed and simplified IPv6 address and mask parsing
* Made help text / man page more consistent
* Dropped ethtool-copy.h patch as upstream is now newer

Edward Cree (2):
  Add IPv6 support to NFC

Leaves 'src-ip' and 'dst-ip' documented as taking x.x.x.x, because there's
more low-level nroff here than I can parse, let alone emit.

Applied these two, and added the patch below.  Thanks for your

Change IP parameter syntax in documentation to just 'ip-address'

Writing out the IPv4 address syntax repeatedly is not really
necessary, and extending it to cover IPv6 addresses will just make the
documentation harder to read.
