The r39147 commit introduces a regression: at lease on some routers
with ar8216 switch large packets get lost if 802.1q tagged port is
used on the interface connected to the aforementioned switch.
The r39147 changes code in the way so interface is set to accept
packets no longer than max ethernet frame length for a given mtu.
Unfortunately ar8216 has a feature: it sends two additional bytes
as a packet header and those this header needs to be added to the
max frame length. Otherwise long enough packets get lost.
The problem only manuifests itself if interface is used in vlan
tagged mode. If interface is untagged then ar8216's header fits
into space used by 802.1q tag and not packets are lost.
Include two additional bytes in the max frame length calculation
to fix the issue.
This patch is tested and works with Trendnet TEW-632BRP.

The built-in wireless MAC of the AR934x SoC can handle
external LNAs and the control signal of the LNAs can be
routed to any GPIO line. Add a helper function which
can be used to configure the GPIO lines.
The helper function will be used for AR934x boards
which are using externel LNAs to improve sensitivity.

The LNAs need to be enabled by setting their respective GPIO to high even
though the original firmware's setting sets them to low on initialization.
Obviously the LNAs are then later initialized by the driver on the OEM
firmware. Without this fix the device is mostly "deaf".

The PHY always says there is no link
Instead of doing this dma sync a mdelay does the same trick and it is as unreliable.

The hardware supports large ethernet frames. Override
the maximum frame length and packet lenght mask in the
platform data to allow to use large MTU on the ethernet
interfaces.
Limit the feature to AR934x SoCs for now. It should work
on some other SoCs as well, but those has not been tested
yet.

The currently used bitmask of the maximum frame length field
is wrong for both models. On AR724x/AR933x the largest frame
size is 2047 bytes, on the AR934x it is 16383 bytes.
Make the MTU setup code model specific, and use the correct
bitmask for both models. Also change the value to the maximum.

Set the MAX_FRAME_LEN register to zero in ag71xx_hw_init()
and write the correct value into that from the ag71xx_open()
and ag71xx_fast_reset() functions.
Also recalculate the RX buffer size based on the actual
maximum frame length value to optimize memory allocation.
Additionaly, disallow to change the MTU value while the
interface it running.

The currently used bitmask is not correct for all SoCs.
Introduce a new field in struct ag71xx and store the
bitmask in that. Use the current value for now, it will
be adjusted for each SoCs in further patches.
Aslo use the new field directly in the ag71xx_rx_packets
and ag71xx_hard_start_xmit() functions and remove the
ag71xx_desc_pktlen() helper.
