We currently use more ore less evil hacks (slow_msp_audio sysctl) to
configure the various variants of these chips in order to have
stereo autodetection work. Nevertheless, this doesn't always work
even though it _should_, according to the specs.
This is, for example, the case for some popular Hauppauge models sold
sold in Germany.
However, the Linux driver always worked for me and others. Looking at
the sourcecode you will find that the linux-driver uses a very much
enhanced approach to program the various msp34xx chipset variants,
which is also found in the specs for these chips.
This is a port of the Linux MSP34xx code, written by Gerd Knorr
<kraxel@bytesex.org>, who agreed to re-release his code under a
BSD license for this port.
A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required
to enable the new driver. Otherwise the old code is used.
The msp34xx.c file is diff-reduced to the linux-driver to make later
modifications easier, thus it doesn't follow style(9) in most cases.

workaround is to route the card function interrupt to IRQ1. It
appears from my testing that this is an acceptable workaround for most
chipsets (there's still some issue with the ricoh chipset).
Also, only look at the NOT_A_CARD bit when the bridge tells us there's

1) When the bridge tells us that we have a card that isn't recognized, we
use the force register to force the CV_TEST to run. This test causes the
bridge to re-evaluate the card. Once this re-evaluation process happens,
we get a new interrupt that may say it is ready to process. We try this up
to 20 times. Tests have shown that this appears to correctly reset the
'Unknown card type' problem that I saw on my Sony PCG-505TS.
2) Take a page from OLDCARD and always read the CSC register in the ISR.
Some TI (and it seems maybe Ricoh) chipsets require this to behave
properly. This work around appears to work due to some power management
protocols that were improperly implemented. Maybe it can be removed when
this driver supports the full PME# protocol described in the standards.

1. The initialisation command does not work in interrupt mode. Whether
this is a firmware bug or a feature is not clear. The original Fore
drivers execute the initialize command always in polling mode, so
it appears that this behaviour is expected. When we detect a 4.X.Y
firmware do busy wait on the command status.
2. The command code of the GET_PROM command has changed. This is an
unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
in 4.X.Y (although unimplemented in the firmware). We need to
use the correct code depending on the firmware.
3. The 4.X.Y firmware can set the error flag in the command status
without also setting the completion flag (as the documenation says).
Check both variants.
An additional field in the per-card structure fu_ft4 is TRUE when we have

For some reason that I don't fully understand, the 5701 signals PCS
encoding errors as though they were link change events, i.e. the 'link
state changed' bit in the status word of the status block is updated
and an interrupt is generated. This would cause the bge_tick() function
to be invoked and a "gigabit link up" message to be printed on the console.
To avoid this, the interrupt handler now checks the MAC status register
when a link change interrupt is triggered, and it will only call the
bge_tick() function if the 'PCS encoding error detected' bit is clear.
(This change should have no effect on copper NICs since this bit can
only ever be set in TBI mode. I do not know how it affects 5704 NICs
