Previously hostapd would not stop transmitting when a DFS event was
detected and no available channel to switch to was available.
Disable and re-enable the interface to enter DFS state. This way, TX
does not happen until the kernel notifies hostapd about the NOP
expiring.

Currently a device which has a DFS channel selected using the UCI
channel setting might switch to a non-DFS channel in case no chanlist is
provided (UCI setting "channels") when the radio detects a DFS event.
Automatically add a chanlist consisting of the configured channel when
the device does not operate in auto-channel mode and no chanlist set to
circumvent this issue.

Similar to wireguard, vxlan can configure multiple peers or add specific
entries to the fdb for a single mac address.
While you can still use peeraddr/peer6addr option within the proto
vxlan/vxlan6 section to not break existing configurations, this patch
allows to add multiple sections that conigure fdb entries via the bridge
command. As such, the bridge command is now a dependency of the vxlan
package. (To be honest without the bridge command available, vxlan isn't
very much fun to use or debug at all)
Field names are taken direclty from the bridge command.
Example with all supported parameters, since this hasn't been documented so
far:
config interface 'vx0'
option proto 'vxlan6' # use vxlan over ipv6
# main options
option ip6addr '2001:db8::1' # listen address
option tunlink 'wan6' # optional if listen address given
option peer6addr '2001:db8::2' # now optional
option port '8472' # this is the standard port under linux
option vid '42' # VXLAN Network Identifier to use
option mtu '1430' # vxlan6 has 70 bytes overhead
# extra options
option rxcsum '0' # allow receiving packets without checksum
option txcsum '0' # send packets without checksum
option ttl '16' # specifies the TTL value for outgoing packets
option tos '0' # specifies the TOS value for outgoing packets
option macaddr '11:22:33:44:55:66' # optional, manually specify mac
# default is a random address
Single peer with head-end replication. Corresponds to the following call
to bridge:
$ bridge fdb append 00:00:00:00:00:00 dev vx0 dst 2001:db8::3
config vxlan_peer
option vxlan 'vx0'
option dst '2001:db8::3' # always required
For multiple peers, this section can be repeated for each dst address.
It's possible to specify a multicast address as destination. Useful when
multicast routing is available or within one lan segment:
config vxlan_peer
option vxlan 'vx0'
option dst 'ff02::1337' # multicast group to join.
# all bum traffic will be send there
option via 'eth1' # for multicast, an outgoing interface needs
# to be specified
All available peer options for completeness:
config vxlan_peer
option vxlan 'vx0' # the interface to configure
option lladdr 'aa:bb:cc:dd:ee:ff' # specific mac,
option dst '2001:db8::4' # connected to this peer
option via 'eth0.1' # use this interface only
option port '4789' # use different port for this peer
option vni '23' # override vni for this peer
option src_vni '123' # see man 3 bridge

vxlan can be configured without a peer address. This is used to prepare
an interface and add peers later.

This fixes a nasty problem introduced in 2.81 which causes random
crashes on systems where there's significant DNS activity over TCP. It
also fixes DNSSEC validation problems with zero-TTL DNSKEY and DS
records.
