tr_init() and tr_stop() were missing in trunk_lb_attach().

to the new MAC. But subsequently added ports were still being assigned the
old MAC address because it was copied from the wrong place. Give newly added
trunk ports the current MAC of the master port, rather than the saved MAC of
the master port. The saved MAC should only be used to restore the original
MAC address of the interface when it is removed from the trunk.

sysctl.h was reliant on this particular include, and many drivers included
sysctl.h unnecessarily. remove sysctl.h or add proc.h as needed.

this prevents the ultimate length of the queue of the underlying interface
from being artificially inflated while hte vlan/trunk queue is filled and
then dumped wholesale on the underlying interface, which will dump its
massive queue wholesale on the chip.
tx mitigation is only triggered on real interfaces now (which is where the
cost is)

interfaces down to the queue on the physical interface immediately.
this avoids having the tx mitigation code wasting cpu time dicking around
with simply shuffling packets off virtual interface queues and lets it
do its job of ammortising the cost of calling a real interfaces start
routine.
it also prevents an artificial inflation of the physical interfaces queue
length where packets could hide on the virtual interfaces queues during
softnet before being dumped en masse onto the hardware. this will smooth
out the rate at which packets are submitted to the hardware.

Move calling ether_ioctl() from the top of the ioctl function, which
at the moment does absolutely nothing, to the default switch case.
Thus allowing drivers to define their own ioctl handlers and then
falling back on ether_ioctl(). The only functional change this results
in at the moment is having all Ethernet drivers returning the proper
errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown
ioctl's.

- don't use in-kernel IFMEDIA ioctls in lacp and remove two KASSERTs
that caused reliable panics - the lacp key can be locally assigned and
we don't need to query the media subtype here.
- unbreak failover/loadbalance/broadcast status handling.

This makes it easier to add trunk protocols that consume some packets.
Add a special case for the failover protocol, to prevent shoving
duplicates to bpf. (Not beautiful, but it has to do for the moment).

for future work. also move the repeated tx start code into a common
function.
parts of it are merged from FreeBSD's trunk(4) port. oh, wait... they
renamed it to 'lagg(4)' because a little green guy from Cizzco-Eeeh
told them "trunk is for VLANs, trunk is for VLANs". Bad FreeBSD, don't
listen to the little green guy from Cizzco-Eeeh!
