[nft PATCH v3 0/4] Implement --echo option

[Phil Sutter <phil@nwl.cc>]

Long description of what it is and how it works in patch 3. Patches 1
and 2 are dependencies to patch 3.

I noticed that netlink_events_*_cb() functions accept 'type' parameter
as signed integer, which allows to pass a negative value to enable echo
printing mode without the risk of colliding with one of
nf_tables_msg_types values.

Another change since v2 is a minor fix of the added documentation in
nft.xml - I used <cmd> tag which is not known.

Phil Sutter (4):
  mnl: Consolidate mnl_batch_talk() parameters
  netlink: Pass nlmsg flags from rule.c
  Implement --echo option
  tests: Add a simple test suite for --echo option
