 1.6  12-Feb-2023  kardel PR kern/55654:
Switch default for parameter npf ip4.reassembly to 1.
This makes the NPF default configuration comply with host
requirements for IPv4.
 1.5  28-Apr-2022  martin branches: 1.5.4;
Make the thmap(9) used for params use sleepable allocations,
suggested by rmind@. Should fix PR 56802.
 1.4  28-Apr-2022  martin Temporary hack to make PR 56802 (when it happens) tell us for sure that
it is caused by KM_NOSLEEP memory allocation failure.
 1.3  30-May-2020  rmind Major NPF improvements (merge from upstream):

- Switch to the C11-style atomic primitives using atomic_loadstore(9).

- npfkern: introduce the 'state.key.interface' and 'state.key.direction'
settings. Users can now choose whether the connection state should be
strictly per-interface or global at the configuration level. Keep NAT
logic to be always per-interface, though.

- npfkern: rewrite the G/C worker logic and make it self-tuning.

- npfkern and libnpf: multiple bug fixes; add param exporting; introduce
more parameters. Remove npf_nvlist_{copyin,copyout}() functions and
refactor npfctl_load_nvlist() with others; add npfctl_run_op() to have
a single entry point for operations. Introduce npf_flow_t and clean up
some code.

- npfctl: lots of fixes for the 'npfctl show' logic; make 'npfctl list'
more informative; misc usability improvements and more user-friendly
error messages.

- Amend and improve the manual pages.
 1.2  11-Aug-2019  rmind branches: 1.2.8;
Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.
 1.1  23-Jul-2019  rmind branches: 1.1.2;
NPF improvements:
- Add support for dynamic NETMAP algorithm (stateful net-to-net).
- Add most of the support for the dynamic NAT rules; a little bit more
userland work is needed to finish this up and enable.
- Replace 'stateful-ends' with more permissive 'stateful-all'.
- Add various tunable parameters and document them, see npf-params(7).
- Reduce the memory usage of the connection state table (conndb).
- Portmap rewrite: use memory more efficiently, handle addresses dynamically.
- Bug fix: add splsoftnet()/splx() around the thmap writers and comment.
- npftest: clean up and simplify; fix some memleaks to make ASAN happy.
