0495324b9b mac80211: make sure existing iface belongs to correct (fullmac) phy
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
mac80211 changes.

23a885bf89 mac80211: do not try to setup hostapd-managed interfaces.
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.

3d6c571083 mac80211: add support for wds_bridge hostapd feature
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.

4a03347545 mac80211: gracefully handle preexisting VIF
Gracefully handle cases where the to-be-created wireless interface already
exists on the system which might commonly happen with non-multi-SSID capable
wireless drivers.

This fixes commit 8301e61365 which caused
previously ignored "Too many open files in system (-23)" errors to fail the
wireless setup procedure.

With the updated approach we'll still try recreating the vif after one
second if the first attempt to do so failed with ENFILE but we will now
consider the operation successfull if a second attempt still yields ENFILE
with the requested ifname already existing on the system.

mac80211, hostapd: always explicitly set beacon interval
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.

8301e61365 mac80211: Fix race condition leading to wifi interfaces not coming up at boot sometimes.
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.

Tue Mar 14 04:21:57 2017 daemon.notice netifd: radio1 (2767): command failed: Too many open files in system (-23)

This was a long-standing issue existing since at least OpenWrt Backfire,
and today I finally managed to debug and (hopefully) solve it.
It was happening very few times on most devices; but it was happening
a lot more frequently on fast platforms with multiple radios, such as
the powerpc-based dual-ath9k-radio tl-wdr4900-v1.

5f8f8a3661 base-files, mac80211, broadcom-wl: wifi detection and configuration
Currently, the wifi detection script is executed as part of
the (early) boot process. Pluggable wifi USB devices, which
are inserted at a later time are not automatically
detected and therefore they don't show up in LuCI.

A user has to deal with wifi detection manually, or restart
the router.

However, the current "sleep 1" window - which the boot
process waits for wifi devices to "settle down" - is too
short to detect wifi devices for some routers anyway.

For example, this can happen with USB WLAN devices on the
WNDR4700. This is because the usb controller needs to load
its firmware from UBI and initialize, before it can operate.

The issue can be seen on a BT HomeHub 5A as well as soon as
the caldata are on an ubi volume. This is because the ath9k
card has to be initialized by owl-loader first. Which has to
wait for the firmware extraction script to retrieve the pci
initialization values inside the caldata.

This patch moves the wifi configuration to hotplug scripts.
For mac80211, the wifi configuration will now automatically
run any time a "ieee80211" device is added. Likewise
broadcom-wl's script checks for new "net" devices which
have the "wl$NUMBER" moniker.

Issues with spawning multiple interface configuration - in
case the detection script is run concurrently - have been
resolved by using a named section for the initial
configuration. Concurrent configuration scripts will now
simply overwrite the same existing configuration.

A workaround which preserves the "sleep 1" window for just
the first boot has been added. This allows the existing
brcm47xx boot and mvebu uci-default scripts to correctly
setup the initial mac addresses and regulatory domain.

And finally, the patch renames the "wifi detect" into
"wifi config". As the script no longer produces any output
that has to be redirected or appended to the configuration
file.

Thanks to Martin Blumenstingl for helping with the implementation
and testing of the patch.

5e35b4562f base-files, mac80211, broadcom-wl: use uci to populate wireless config
Previously, wifi detect simply dumped its generated wireless
configuration to STDOUT. A second step was needed to append
the configuration to /etc/config/wireless (or create it, if
it didn't exist).

With this patch, The wifi detection script will now use uci
to update the wireless configuration directly.

This patch also makes the initially created wifi-iface a
named section ('default_radio$X' for mac80211 and
'default_wl$X' for broadcom). With this change, uci will
not print the cfgHASH to STDOUT (which would now corrupt
the wireless configuration). It will also prevent adding
duplicated wifi interface configurations, if the wifi
configuration is run concurrently.
