sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.
Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.
In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported. In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.
While ng_fec called the ioctl to let interfaces in the bundle know
the list of multicast addresses had changed, it never actually
updated that list on the interfaces in the bundle. Consequently,
the multicast filters could be programmed incorrectly.
if_lagg does this correctly, by maintaining a list of addresses
that it has added to interfaces in the bundle. This commit basically
takes the if_lagg code and adds it to ng_fec.
A version of this patch for RELENG_6 has fixed some problems with
IPv6 ND over ng_fec. This is probably the problem in PR 107523.

protocol entry points using functions named proto_getsockaddr and
proto_getpeeraddr rather than proto_setsockaddr and proto_setpeeraddr.
While it's true that sockaddrs are allocated and set, the net effect is
to retrieve (get) the socket address or peer address from a socket, not
set it, so align names to that intent.

this sequence numbers of all links are getting updated on every
successful packet reassembling.

- Changed bytesInQueue calculation math to have more precise information
about links utilization.
- Taken rough account of the link overhead. Better way to do it could be to
get exact overhead from user-level, but I have not done it to keep
binary compatibility.

This has been implemented in such a way as to be backwards ABI compatible.
Kernel consumers are changed to use if_delmulti_ifma(); in_delmulti()

With this architectural change, the panics FreeBSD users have experienced

from whoever has dequeued the item from the queue. Generally they have
no interest in the result, and even if it is called by the queuer, it
should still pretend that it was queued. The queuer should be assuming
that the call was queued and giving them the false confidence that they
are getting status leads to hard to find bugs.
Make it a void and remove all the code that tried to return status through it.
to embed up to four counters in outgoing packets. The message specifies
the offset at which the counter should be inserted as well as the
parameters of the counter.
Example usage:
ngctl msg src0: setcounter \

to embed a timestamp (struct timeval) in outgoing packets. The message
specifies the offset at which the timestamp should be inserted.
NG_SOURCE(4) gives an example usage that queues an ICMP packet. Using that
example, the following command will insert a timestamp in the ICMP's data
payload:
ngctl msg src0: settimestamp '{ offset=0x2a flags=1 }'
