As TP-Link 841v10 are not supported by gluon 2015.1.x, they need to
  be feed with the experimental firmware. Since the experimental firmware
  could break a router, we want these aliens to update only from stable
  versions.

As '/lib/netifd/hostapd.sh' and '/lib/wifi/mac80211.sh' should never be
called directly (but only be included from other files like '/lib/netifd/
wireless/mac80211.sh', these files do not need to have an execute bit
set, which on the other hand would be ensured by using the
$(INSTALL_BIN) macro in the make file. The $(CP) macro would simply copy
the files from the package into the image and preserve their
permissions.

For an so far unknown reason one of the nodes in the testing stream had
an additional open WLAN called 'OpenWrt' after updating from v0.5.3 to
v0.6.0~rc2. It has to be mentioned, though, that this node used a
heavily customized network configuration prior to the update to fullfil
some very specific needs.

It should however be avoided that a new network suddenly appears after
applying an update in any case. As a cause for this, the mac80211.sh
located in '/lib/wifi/' has been identified, which scans for unknown
PHYs when executed and adds them along with such an example network to
'/etc/config/wireless'. For a pure OpenWRT router this behaviour is not
that much a problem, as the radio itself gets deactivated by adding an
"option disabled '1'" that must be removed manually by a user. In comb-
ination with Gluon this becomes critical, as the gluon-mesh-batman-adv-
core package would enable the radio automatically, such that a node can
connect to other Freifunk nodes over WiFi. Generally, a network
'OpenWrt' should not exist anymore in '/etc/config/wireless' by that
time. The reason for which in the case mentioned above there was such
an entry is still unknown.

In order to exclude such a security risk, for now we provide a modified
copy of '/lib/wifi/mac802111.sh' with this packages, in which the
corresponding lines to add a default/example network 'OpenWrt' have been
removed compeletely. This modified version of the script replaces the
original script at build-time.

As it turned out, the old hostapd.sh from BB does not provide all the
necessary functions needed by the mac80211.sh that got added in commit
f2d78863. The corresponding hostapd.sh
from the CC trunk [1] however has this functions and works fine in BB
already. Hence, we add the netifd.sh from [1] into the package because
of the fixes in mac80211.sh in CC that did not get backported to BB
(yet). netifd.sh gets renamed to hostapd.sh by the Makefile for the
hostapd package and copied to /lib/netifd.

As mentioned in [1], the hwmodes "11ng" and "11na" are no longer valid
in BB and become "11g" and "11a". Enabling 802.11n modes are set via the
htmode option now.

Moreover, as the version of BB we rely on with Gluon v2014.4 comes with
a faulty setup script for mac80211 that prevents setting of htmode in
adhoc mode, we replace the default script with a newer one from [2].
Additionally, the mcast_rate value did not get applied correctly in the
BB base of v2014.4, which gets fixed by this exchange as well.

The package by now was rather aimed to target on the migration of
TP-Link TL-WR1043NDv2 devices from a pseudo-stable firmware to the
officially stable version 0.6.0.

However, as it might become necessary to change other configuration
values from AA to be compliant with their corresponding values in BB
independent from the particular hardware-type, the package got renamed
to reflect this use. Moreover, as there only is the need to migrate
TP-Link TL-WR1043NDv2 devices once, with the new name the package can be
reused for the migration to Chaos Calmer by adapting the included
scripts.
