The goal of the series is to simplify and make it possible to use
ncdevmem in an automated way from the ksft python wrapper.

ncdevmem is slowly mutated into a state where it uses stdout
to print the payload and the python wrapper is added to
make sure the arrived payload matches the expected one.

v7:
- fix validation (Mina)
- add support for working with non ::ffff-prefixed addresses (Mina)

v6:
- fix compilation issue in 'Unify error handling' patch (Jakub)

v5:
- properly handle errors from inet_pton() and socket() (Paolo)
- remove unneeded import from python selftest (Paolo)

v4:
- keep usage example with validation (Mina)
- fix compilation issue in one patch (s/start_queues/start_queue/)

v3:
- keep and refine the comment about ncdevmem invocation (Mina)
- add the comment about not enforcing exit status for ntuple reset (Mina)
- make configure_headersplit more robust (Mina)
- use num_queues/2 in selftest and let the users override it (Mina)
- remove memory_provider.memcpy_to_device (Mina)
- keep ksft as is (don't use -v validate flags): we are gonna
  need a --debug-disable flag to make it less chatty; otherwise
  it times out when sending too much data; so leaving it as
  a separate follow up

v2:
- don't remove validation (Mina)
- keep 5-tuple flow steering but use it only when -c is provided (Mina)
- remove separate flag for probing (Mina)
- move ncdevmem under drivers/net/hw, not drivers/net (Jakub)
