'non-wildcard' interfaces enables dnsmasq's '--bind-dynamic' mode. This

Quoting dnsmasq's author "bind-dynamic (bind individual addresses, keep
up with changes in interface config) ... On linux, there's actually no
sane reason not to use --bind-dynamic, and it's only not the default for
historical reasons."

This patch makes possible to tweak the downstream SNR margin on
Lantiq DSL devices.
The UCI parameter 'network.dsl.ds_snr_offset' is used to set the SNR
margin offset. It accepts values in range -50 to +50 in 0.1 dB units.
The SNR margin can thus be modified in range -5.0 to +5.0 dB in 0.1 dB
steps.
Currently this should only affect ADSL (not VDSL). It should be very
easy to make this work also on VDSL lines, but since I couldn't test
on VDSL lines this patch does not do that yet.
I have also a patch for LUCI about this, that I could submit.

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.

When sta is configured, hostapd receives 'stop' and 'update' command from
wpa_supplicant. In the update command, hostapd gets sta parameters with
which it configures ap.
Problem is, with the default wireless configuration:
mode:11g freq:2.4GHz channel:1
If sta is connected to 5GHz network, then ap does not work. Ideally with
340-reload_freq_change.patch hostapd should reload the frequency changes
and start ap in 5GHz, but ap becomes invisible in the network.
This issue can be reproduced with following /etc/config/wireless:
config wifi-device radio0
option type mac80211
option channel 1
option hwmode 11g
option path 'virtual/uccp420/uccwlan'
option htmode 'none'
config wifi-iface 'ap'
option device 'radio0'
option encryption 'none'
option mode 'ap'
option network 'ap'
option ssid 'MyTestNet'
option encryption none
config wifi-iface 'sta'
option device radio0
option network sta
option mode sta
option ssid TestNet-5G
option encryption psk2
option key 12345

received from wpa_supplicant. Also prepare rates table after frequency

When the remote site of an openvpn connection goes down for some time
