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)
