eee8ab59dc ltq-vdsl-mei: reset g_tx_link_rate on showtime exit
Without this change, ifx_mei_atm_showtime_check() will always return
"showtime" after one call of MEI_InternalXtmSwhowtimeEntrySignal()
was done, even if MEI_InternalXtmSwhowtimeExitSignal() was called
in the meantime.

The ifx_mei_atm_showtime_check() function is used by the ltq-atm and
ltq-ptm driver.

17eb826a70 ltq-atm: rewrite tx path to use IRQs
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

d3fd38637f lantiq: create ATM/PTM interfaces with dsl as netdev name
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.
