loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now

All unicast/broadcast/multicast layer2 traffic is blocked so it works much the
same way as using firewall rules but scales better and is generally easier as
firewall packages usually do not allow ARP blocking.
An example usage would be having a number of customers on separate vlans
bridged with a server network. All the vlans are marked private, they can all
communicate with the server network unhindered, but can not exchange any
traffic whatsoever with each other.

Remove IPX over IP tunneling support, which allows IPX routing over IP

o revised channel handling support; ifconfig now queries the kernel to
find the list of available channels and handles channel promotion;
channel attributes can be specified as part of the channel; e.g. 36:a
for channel 36 in 11a (as opposed to turbo A or HT A)
o use channel list to map between freq and IEEE channel #; this eliminates
all knowledge of how the mapping is done and fixes handling of cases
where channels overlap in the IEEE channel # space but are distinct in
the frequency+attributes space (e.g. PSB)
o add new knobs: bgscan, ff (Atheors fast frames), dturbo (Atheros
Dynamic Turbo mode), bgscanidle, bgscanintvl, scanvalid, roam:rssi11a,
roam:rssi11b, roam:rssi11g, roam:rate11a, roam:rate11b, roam:rate11g

The name trunk is misused as the networking term trunk means carrying multiple
VLANs over a single connection. The IEEE standard for link aggregation (802.3
section 3) does not talk about 'trunk' at all while it is used throughout IEEE
802.1Q in describing vlans.
The lagg(4) driver provides link aggregation, failover and fault tolerance.

tolerance. This driver allows aggregation of multiple network interfaces as
one virtual interface using a number of different protocols/algorithms.
failover - Sends traffic through the secondary port if the master becomes
inactive.
fec - Supports Cisco Fast EtherChannel.
lacp - Supports the IEEE 802.3ad Link Aggregation Control Protocol
(LACP) and the Marker Protocol.
loadbalance - Static loadbalancing using an outgoing hash.
roundrobin - Distributes outgoing traffic using a round-robin scheduler
through all active ports.
This code was obtained from OpenBSD and this also includes 802.3ad LACP support
from agr(4) in NetBSD.

new interface. In other cases loading the module is unwanted and
can lead to ill side effects. One such effect found is as follows:
"kldunload if_foo" tells the module to kill all its interfaces,
which results in messages sent to devd; the module unloads. Then
devd starts processing the messages, which ends up in a etc script
running ifconfig fooX, which reloads the module.
'-alias', and that 'add' and 'delete are in fact synonyms for these
in the ifconfig(8) grammar.

address learned by the bridge is made permanent, the address will not age out
and most importantly will not migrate to another interface.
This can be used to stop mac address poisoning or clients roaming in much the
same way as static entries without the hassle of preloading the table.
RSTP provides faster spanning tree convergence, the protocol will exchange
information with neighboring switches to quickly transition to forwarding
without creating loops. The code will default to RSTP mode but will downgrade
any port connected to a legacy STP network so is fully backward compatible.

This should allow for control over the relative order of processing

Presently, ifconfig callbacks are used for L2 configuration, media
and vlan, so actions associated with address assignment, like sending
out a gratuitous ARP, should go when L2 is running already.
This also should fix the problem with setting up vlan interfaces
from rc.conf, when both IP and vlan+vlandev parameters are passed
to ifconfig at once.
Future work: Consider introducing several ifconfig callback lists
to invoke callbacks orderly.
