8b15e7f661 mac80211: add support for multiple wiphys behind a single device
The device path will be the same for the first phy. For all subsequent
phys, the path gets an extra +1, +2, ...
Move the code for converting path to phy and vice versa to a separate
library script shared by config detection code and the netifd wireless
handler script

a5ec41b0e5 mac80211: add new acs_exclude_dfs option
The channel can be selected automatically at run time by setting
channel=acs_survey or channel=0, both of which will enable the ACS survey
based algorithm in hostapd. If the option acs_exclude_dfs is set in the
hostpad config DFS channels from ACS are excluded on channel selection.

This commit will add the possibilty to exclude the dfs channel on ACS
survey.

Refactor mesh initialization into a separate function, do some cleaning

Changes:
 * Move iw mesh setup to new mac80211_setup_mesh()
 * fallback on 'ssid' parameter in case 'mesh_id' isn't set
 * move setting of freq variable to shared code as it is needed for

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.

Fixes FS#664, FS#704.

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.

Fixes FS#619.

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.

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.

daaed6f251 netifd: fix start_disabled 'sh: bad number' in mac80211 setup (bug #19345)
Two errors "netifd: radio0: sh: bad number" have recently surfaced in system
log in trunk when wifi interfaces come up. I tracked the errors to checking
numerical values of some config options without ensuring that the option has
any value.

The errors I see have apparently been introduced by r45051 (ieee80211r in
hostapd) and r45326 (start_disabled in mac80211). My patches fix two
instances of "bad number", but there may be a third one, as the original
report in bug 19345 pre-dates r45326 and already has two "bad number" errors
for radio0.

a0cc6803c8 mac80211: Revert adding SM Power Save capability to hostapd configuration
Part of rev 44173 added setting the SM Power Save capability in the hostapd.conf
file if the driver indicated that it was supported. It appears this was
incorrect, because the field in the actual HT Capabilities field in the AP
configuration is really a state indication. Just copying the state from the
capability resulted in the AP indicating that it had SMPS enabled all the time
if it supported SMPS. This effectively just disables all clients from sending
packets to the AP with more than one spatial stream, for no good reason.
So remove this part of the change.
