str has already been tested. It seems that this test should be on the
recently returned value snr.
A simplified version of the semantic match that finds this problem is as
follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r exists@
local idexpression x;
expression E;
@@
if (x == NULL || ...) { ... when forall
return ...; }
... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\)
(
*x == NULL
|
*x != NULL
)
// </smpl>

This is the second go through of the old DMA_nBIT_MASK macro,and there're not
so many of them left,so I put them into one patch.I hope this is the last round.
After this the definition of the old DMA_nBIT_MASK macro could be removed.

Error handling code following a kmalloc should free the allocated data.

I don't much like the trick with multiple inclusions of solos-attrlist.c
but don't really see a saner way to do it without repeating the list.

There are still a _lot_ of attributes, but for at least the basic ones
we want to be able to get/set them from the kernel. Especially the ones
we want to inform the ATM core about (link state, speed).

We no longer try to load firmware while the ATM is up and running.
However, this means that we _do_ make init_module() wait for it, and it
takes a long time for now (since we're using ultra-conservative code in
the FPGA for that too).
The inner loop which uses swahb32p() was by Simon Farnsworth.
Simon has patches which migrate us to request_firmware_nowait(), for
which we'll actually need to take down the ATM devices, do the upgrade,
then reregister them.

Print a message if pskb_expand_head fails.
Make atmdebug writable by root, so that you can turn printing of data sent to
and received from the card on and off at runtime - useful for tracking
corruption.

The length field shouldn't ever include the size of the header itself.
This fixes the problem that some people were seeing with 1500-byte
packets.
