as one can see on the huge jump, it's very plausible that firmware does not report the

This patch makes usage of the results from disconnected antenna alg to
know how many antennas are connected.
It also synchronizes between the chain noise alg and the W/A that
disables power management during association. All the antennas must be
enables during the chain noise algorithm. Hence, power management is
restored only after the completion of the algorithm.
In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

This makes injection work on iwl4965 and iwl5000. Tested on both cards.
Note: To inject management frames with encryption, HW crypto support
must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1"

(or: LowerMAC Protocol Rev: 5.5 )
And this is a big win, since:

* no problems anymore with packages > 1399 octets (without lowering the MTU).
* monitor mode finally works on USB for more than just a few seconds.

On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or

error codes and, with or without it, there just isn't much reason to
do WARN_ON() on it. Even if error code is not set there, core EH
logic won't have any problem dealing with the error condition.

of them being unifying probing, hotplug and EH reset paths uniform.
Previously, broken hardreset could go unnoticed as it wasn't used
during probing but when something goes wrong or after hotplug the
problem will surface and bite hard.
OSDL bug 11195 reports that sata_nv generic flavor falls into this
category. Hardreset itself succeeds but PHY stays offline after
hardreset. I tried longer debounce timing but the result was the
same.
http://bugzilla.kernel.org/show_bug.cgi?id=11195
So, it seems we'll have to drop hardreset from the generic flavor.

I've been chasing Jeff about this for months. Jeff added the Marvell
device identifiers to the ahci driver without making the AHCI driver
handle the PATA port. This means a lot of users can't use current
kernels and in most distro cases can't even install.
This has been going on since March 2008 for the 6121 Marvell, and late 2007
for the 6145!!!
This was all pointed out at the time and repeatedly ignored. Bugs assigned
to Jeff about this are ignored also.
To quote Jeff in email
> "Just switch the order of 'ahci' and 'pata_marvell' in
> /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.
> See? It's not rocket science, and the current configuration can be

(Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
breaks at install time is in fact impossible)
To quote Jeff in August 2007
> " mv-ahci-pata
> Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller
> command' area before it is usable, and can go upstream."
Only he add the ids anyway later and caused regressions, adding a further
id in March causing more regresions.
The actual fix for the moment is very simple. If the user has included
the pata_marvell driver let it drive the ports. If they've only selected
for SATA support give them the AHCI driver which will run the port a fraction
faster. Allow the user to control this decision via ahci.marvell_enable as
a module parameter so that distributions can ship 'it works' defaults and
smarter users (or config tools) can then flip it over it desired.

The current check for monotonicity is way too weak: Andreas Mohr reports (
http://lkml.org/lkml/2008/8/10/77 ) that on one of his test systems the
current check only triggers in 50% of all cases, leading to catastrophic
timer behaviour. To fix this issue, expand the check for monotonicity by
doing ten consecutive tests instead of one.
