84b3932bf0 [PATCH] forcedeth: fix multi irq issues
With Manfred Spraul <manfred@colorfullife.com> and
     Andrew Morton <akpm@osdl.org>

Bring back this recently-reverted patch, only fixed.

Original changelog:

    From: Ayaz Abdulla <aabdulla@nvidia.com>

    This patch fixes the issues with multiple irqs.

    I am resending based on feedback. I decoupled the dma mask for
    consistent memory and fixed leak with multiple irq in error path.

    Thanks to Manfred for catching the spin lock problem.

Fix it:

    From: Manfred Spraul <manfred@colorfullife.com>

    Fix bug introduced by ebf34c9b6f, covered in
    http://bugzilla.kernel.org/show_bug.cgi?id=6568.

    Remove second instance of the request_irq() calls: they were moved
    from nv_open into nv_request_irq.

    Thanks to Alistair Strachan <alistair@devzero.co.uk> for reporting and
    persisting.

ee7abb04df [PATCH] sky2: allow dual port usage
If both ports are receiving on the SysKonnect dual port cards,
then it appears the bus interface unit can give an interrupt status
for frame before DMA has completed.  This leads to bogus frames
and general confusion. This is why receive checksumming is also
messed up on dual port cards.

A workaround for the out of order receive problem is to eliminating
split transactions on PCI-X.

This version is based of the current linux-2.6.git including earlier
patch to disable dual ports.

843a46f423 sky2: prevent dual port receiver problems
When both ports are receiving simultaneously, the receive logic gets confused
and may pass up a packet before it is full. This causes hangs, and IP will see
lots of garbage packets. There is even the potential for data corruption if
a later arriving packet DMA's into freed memory.

It looks like a hardware bug because status arrives for a packet but no
data is there. Until this bug is worked out, block the user from bringing
up both ports at once.

1ea739a5f9 The ixp2000 driver for the enp2611 was developed on a board with
three gigabit ports, but some enp2611 models only have two ports
(and only one onboard PM3386.)  The current driver assumes there
are always three ports and so it doesn't work on the two-port
version of the board at all.

This patch adds a bit of logic to the enp2611 driver to limit the
number of ports to 2 if the second PM3386 isn't detected.

d8e95e52a9 sis900: phy for FoxCon motherboard
661FX7MI-S motherboard which uses the SiS 661FX chipset.  The patch adds
an entry to mii_chip_info for the transceiver.

The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.

Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits.  There were fifth second pauses in refresh of large xterms,
and it made Netrek suck.  I can provide further test data.

Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.

I wasn't able to identify the actual transceiver, so the description
field is a guess.

This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2

I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.

Diff is against 2.6.16.13.
