This is necessary to prevent sk_wmem_alloc of a socket from overflowing,
which leads to ENOBUFS errors on application level.

This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into
account (if set), so that packages do not need to manually override
PKG_BUILD_DIR just to handle variants.
This also updates most base packages with variants to use the updated
default PKG_BUILD_DIR.

This patch re-enables the reset_ppe() functionality for VR9 targets by using
the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function
was taken from the ppa datapath driver of lantiq UGW 7.4.1.
Additionally it adds the required reset definitions to the vr9 dtsi file.
It also prepares the reset_ppe() function calls for the other lantiq targets.
This feature is needed to be able to switch between ltq-atm/ltq-ptm driver
in ATM/PTM Auto-Mode at runtime.

Recent Speedport firmware downloads only work over HTTPS, so the user
either needs to provide the already downloaded file or install
ustream-ssl-* as well as ca-certificates or ca-bundle.
So to get VDSL2 with vectoring on xRX200, simply run
vdsl_fw_install.sh
on the target and either provide the downloaded file as instructed or
make sure the device is connected to the Internet and can download that
HTTPS url itself.

The ATM subsystem is different from the generic ethernet NICs. The ATM
subsystem requires a callback when a packet has been sent. It means a
tx skb_buff need to be used after it has sent. While the generic NIC
can fill up the TX ring and free skb_buffs if it encounter a ring buffer slot
with an already sent skbuff.
The ATM drivers need call the pop() function after it has send a
single ATM package. The ATM subsystem controls via this ways the queuing.
The ppe engine use DMA channels for read and write. Every atm_vcc has it's
own TX DMA channel and each TX DMA channel has it's own ring buffer.
The old driver had multiple issues:
- Call the subsystem callback at the beginning of tx function (ppe_send).
Didn't allowed the ATM subsystem to control the enqueued package
amount.
- Filled up the TX ring until full and fail futher
- copy or decouple the skb from all other subsystem before giving it
over to TX ring
The new tx path uses interupts.
- call the subsystem callback _after_ it was sent by hardware
- no need to copy our decouple the skb any more
- gives back control to the atm subsystem over the enqueued packages
- use an interupt for every sent atm package
Using interupts shouldn't be a problem because of the slow uplink bandwidth of
ADSL.
The speed _through_ the DSL router was always as high as it should
be, only traffic generated on the router itself were affected.
After changing to new tx path, the speed of iperf's run on the
router itself reached the same speed. The master/trunk wasn't as much
affected because of TCP optimisations (reboot-5022-gb2ea46fe236a).
The following results are taken on the remote server, which receives
the stream over the internet and the DSL line.
The sync moves between every sync a litte bit, but is so far stable

Renaming an atm etherbride using 'ip link' (via hotplug) is racy since the
original netdev might disappear before br2684ctl has finished appling it's
setting:
local2.notice br2684ctl[1667]: Interface "nas0" created sucessfully
local2.notice br2684ctl[1667]: Communicating over ATM 0.8.35, encapsulation: LLC
kern.info kernel: dsl0: renamed from nas0
kern.err kernel: br2684:br2684_regvcc: tried to attach to non-existent device
local2.err br2684ctl[1667]: Could not configure interface:No such device or address
By passing the final used netdev name to br2684ctl_wrap another race
condition workaround will be enabled again.
Change the lantiq ptm driver to create a netdev with the name dsl as well.
Albeit the rename via 'ip link' works fine so far, using a different
approach for ptm then atm could be confusing.
