lagg(4): Fix missing IFNET_LOCK acquirement

Set the fastest linkspeed in each physical interface to lagg(4)

branches: 1.18.8;
lagg(4): Safely handle misaligned mbufs.

Optimizing for non-strict-alignment architectures -- without falling
afoul of alignment sanitizers or overeager compilers -- is left as an
exercise for the reader.

PR kern/56894

fix various typos in comment, documentation and log messages.

Move input processing of lagg(4) before ether_input
to get rid of dependence.

This implementation is similar with that of bridge(4).

rename lagg_enqueue to lagg_output

Use addlog(4) for putting 2 messages to one line

Make lagg interface specified "laggproto none" able to up

added log when ifpromisc is failed

Fix to call lacp_linkstate with IFNET_LOCK held

Network stack calls lacp_linkstate through lagg_port_ioctl when
doing "ifconfig up" or "ifconfig down" to an interface that is
a member of lagg(4). And IFNET_LOCK in the member interface
is held while the ioctl.
Therefore, lacp_linkstate is renamed to
lacp_linkstate_ifnet_locked, and always called with IFNET_LOCK
held. It avoids locking agains myself.

lagg: support l2tp(4) aggregation

- Accept "ifconfig lagg* laggport l2tp*"
- Set promiscuous mode when the added interface is l2tp*
- check IFF_UP in addition to IFF_RUNNING on
SIOCSIFFLAGS to a child interface.

Set a port interface of lagg(4) in promiscuous mode
when the lagg(4) is in promiscuous mode.

lagg: update capabilities of ifnet and ethercom

Commonly capabilities of all child interface are configured
to a lagg interface.

lagg: Register lagg_ifdetach to ether_ifdetach hook

Make a link-layer address of lagg(4) configurable by ifconfig(8)

lagg(4) uses a configured link-layer (MAC) address instead
of a random MAC address generated on creating.
The configured MAC address is copied to all child interface
and used for a system id of LACP.
