When compiling this driver, the compiler throws the following warnings:

drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds

This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]).  The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.

The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.

This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Thanks Mikael.

Anonymity has some good attributes.
Blame avoidance is one of them.

I've broad shoulders.  It's me, then Dwight Howard...

There might be another few of these where ->name or ->dev
was used before struct device or net_device was registered.
I'll go back and check.

tulip_core has:

	if (tp->flags & HAS_MEDIA_TABLE) {
		sprintf(dev->name, DRV_NAME "%d", board_idx);	/* hack */
		tulip_parse_eeprom(dev);
		strcpy(dev->name, "eth%d");			/* un-hack */
	}

So I don't feel _too_ bad.

tulip_parse_eeprom is done before register_netdev so the logging
there can not use netdev_<level> or dev_<level>(&dev->dev

I/Q calibration was completely broken, resulting in a high number of CRC errors
on received packets. before i could see around 10% to 20% CRC errors, with this
patch they are between 0% and 3%.

1.) the removal of the mask in commit "ath5k: Fix I/Q calibration
(f1cf2dbd)" resulted in no mask beeing used
when writing the I/Q values into the register. additional errors in the
calculation of the values (see 2.) resulted too high numbers, exceeding the
masks, so wrong values like 0xfffffffe were written. to be safe we should
always use the bitmask when writing parts of a register.

2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we
convert to a signed value later by substracting 128. this resulted in too low
numbers for Q many times, which were limited to -16 by the boundary check later
on.

3.) checked everything against the HAL sources and took over comments and minor
optimizations from there.

4.) we can't use ENABLE_BITS when we want to write a number (the number can
contain zeros). also always write the correction values first and set ENABLE
bit last, like the HAL does.

when using a fixed antenna we should use the antenna number in all tx
descriptors, otherwise the hardware will sometimes send the frame out on the
other antenna. it seems like the hardware does not always respect the default
antenna and diversity settings (esp.  AR5K_STA_ID1_DEFAULT_ANTENNA).

also i would like to note that antenna diversity does not always work correctly
on 5414 (at least) when only one antenna is connected: for example all frames
might be received on antenna A but still the HW tries to send on antenna B some
times, causing packet loss.

this is both verified with the antenna statistics output of the previous patch
and a spectrum analyzer.

VSWITCH or GuestLAN must be configured either in layer2 or in

fails. Trying to recover from this error cannot help; thus

Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory
corruption problem. When initializing the clip groups the code was
mistakenly using the iwlagn rate count, not the 3945 rate count. This
resulted in more memory being written than was allocated.

"iwlwifi: move 3945 clip groups to 3945 data" moved the location where the
clip groups are stored and the impact is now severe in that the number of
configured TX queues is modified. Previously the
"temperature" field was overwritten, which did not seem to affect the
operation.

Fix this one instance where wrong rate count was used. I also noticed one
more location where the iwlagn rate count was used to index an iwl3945
array, fix this. I also modified one location that modified the iwlagn rate
count to obtain the iwl3945 rate count ... just use the iwl3945 rate count
directly.
