In situations with high packet loss, if all sync packets are lost, conflicting
subnets will be configured.
If the network is static, this can be prevented by always using the highest number
of subnets that has been observed.
This assumes no nodes are physically added / removed from the network.
This eliminates race conditions around unregistering netdevs.
gnrc_netreg_lookup-style functions perform a DEVELHELP check on whether
that lock is held.
Model the LoRaWAN integration to GNRC's netif command (ifconfig) as
submodule of it, namely `shell_cmd_gnrc_netif_lorawan`.
This should fix a regression introduced by
https://github.com/RIOT-OS/RIOT/pull/18355
Previously `shell_commands` was a "catch-all" module that included
shell commands for each and every used module that has a shell
companion. Instead, the new `shell_cmds` module is now used to provide
shell commands as individually selectable submodules, e.g.
`cmd_gnrc_icmpv6_echo` now provides the ICMPv6 echo command (a.k.a.
ping).
To still have a "catch all" module to pull in shell commands of modules
already used, `shell_cmds_default` was introduced. `shell_commands`
depends now on `shell_cmds_default` for backward compatibility, but
has been deprecated. New apps should use `shell_cmds_default`
instead.
For a handful of shell commands individual selection was already
possible. Those modules now depend on the corresponding `cmd_%` module
and they have been deprecated.
This adds support for netdevs implementing the new API that provides
`netdev_driver_t::confirm_send()`. This allows implementing netdevs
in an event based non-blocking fashion, making live of driver
developers a bit easier. In addition, `gnrc_tx_sync` will now throttle
users of `sock_udp_send()` so that they can only send datagrams as
fast as the network stack and hardware is able to send out.
Finally, this lays the groundwork to fetch TX statistics (such as
TX timestamps, reception of layer 2 ACKs/NACKs, etc.) from the network
devices.
- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
