This patch adds support for edge triggered irq types. We remove the
locking for irq resources by enable/disable irq and allocate directly
some heap buffer at isr. We have still a enable/disable irq path but
this is for level-triggered irq's which need to be disabled until
spi_async clear the irq line.
There is usually a little race condition between "irq line cleared" and
"enable_irq". When in this time a edge triggered irq arrived, we will
not recognize this interrupt. This case can't happend at at86rf230. The
reason is that we unmask TRX_END irq's only which indicates a transmit
or receive completion, which depends on the current state.
On Transmit:
TRX_END arrived and transceiver is in TX_ARET_ON state again, in this
state no other TRX_END can happen until we leave the state.
On Receive:
This is protected with the RX_SAFE_MODE bit which leaves the transceiver
in RX_AACK_BUSY until we readed the framebuffer. In this state no other
TRX_END can happen.
Tested with RPi where I first detected issues between edge/level irq's.

Whilst the jack is connected we disable the jack detection debounce to
ensure as quick as possible a detection of jack removal. However, it is
only safe to disable the jack debounce whilst the jack is connected if
using the micd clamp or the jack is not inverted. Otherwise spurious

Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.
Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.
Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.

There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
vendor driver supports the CH9100 and CH9200 devices, but the majority of
the code is of the if (ch9100) {} else {} form, with the most significant
difference being that CH9200 provides a real MII interface but CH9100 fakes
one with a bunch of global variables and magic commands. I don't have a
CH9100, so it's probably better if someone who does provides an independent
driver for it. In any case, this is a lightly cleaned up version of the
vendor driver with all the CH9100 code dropped.

Checksum offloading for send and receive is already

adds support for RX and TX hardware checksum offloading
for layer 2 (MAC layer). The hardware calculates the checksum
for IP UDP and TCP packets.
This patch moves the hardware checksum offloading setup
to the set of common functions in qeth_core_main.c.
Layer 2 and layer 3 now simply call the same common functions.
Also note that TX checksum offloading is always enabled.
The device driver relies on the TCP/IP stack to make use of
this feature.
