Some FullMAC cfg80211 wireless devices do not support virtual
interfaces, hence there is script logic to keep the existing network
device. Improve this to support renaming the interface if needed and
make sure the existing interface actually belongs to the right phy.
Change calls to 'iw' to avoid outputing warnings and errors to not
confuse users of such devices.
Also bump PKG_RELEASE which has been forgotten in the previous two

For virtual access points (when multiple SSIDs are used for one
physical AP), there exist one physical network interface and
multiple virtual interfaces, which are fully under control of
hostapd. When networking is setup, the script
`/lib/netifd/wireless/mac80211.sh` is called, which tries to bring
the interface up by a call to `ip link set dev <iface> up`. This
call might fail for virtual APs, because the virtual interface
might not have been created by hostapd yet. There are some artifical
delays in the script most probably to handle this, but when DFS
channel availability check on 5GHz band is issued, hostapd can
delay creating virtual interfaces by a minute.
In order to fix this (or work around it), do not try to bring the
interface up (this is responsibility of hostapd anyway) and
do not try to set txpower on the virtual interface.
Fixes FS#2698.

hostapd allows putting WDS (4addr mode) clients into a separate bridge
other than the bridge regular (3addr mode) clients end up in. This is
useful for example giving WDS clients access to several VLANs
(trunking) while regular clients will end up inside a specific VLAN.
Add 'wds_bridge' config parameter for wifi-iface which contains the
name of the bridge. hostapd-mini already supports this feature, so all
needed is to add the UCI wrapping in mac80211.sh.

With the updated approach we'll still try recreating the vif after one

consider the operation successfull if a second attempt still yields ENFILE
with the requested ifname already existing on the system.

One of the latest mac80211 updates added sanity checks, requiring the
beacon intervals of all VIFs of the same radio to match. This often broke
AP+11s setups, as these modes use different default intervals, at least in
some configurations (observed on ath9k).
Instead of relying on driver or hostapd defaults, change the scripts to
always explicitly set the beacon interval, defaulting to 100. This also
applies the beacon interval to 11s interfaces, which had been forgotten
before. VIF-specific beacon_int setting is removed from hostapd.sh.

In the drv_mac80211_setup function, mac80211_interface_cleanup
is called to ask the kernel to delete all existing interfaces
for the phy that is being configured via netlink.
Later in the first function, mac80211_prepare_vif is called to
set up the new interfaces as required.
But sometimes, when mac80211_prepare_vif (and so the relevant
`iw phy x interface add y` command) runs, the kernel might still
be cleaning up the old interface with the same ifname. It usually
takes very few time to do that; possibly a few milliseconds of
sleep in the script after detecting this error condition could be
enough, but the busybox sh does not support sub-second sleep
intervals.
When this happens, iw obviously fails to create the new interface;
and the following message is printed in the system log, followed by
subsequent failure messages from hostapd in case this would have been
an AP interface.
