At the moment libata doesn't pass pm_message_t down ata_device_suspend.
This causes drives to be powered down when we just want a freeze,
causing unnecessary wear and tear. This patch gets pm_message_t passed
down so that it can be used to determine whether to power down the
drive.

Make ata_set_mode() responsible for determining whether to take port
or device offline on failure.  ata_dev_set_xfermode() and
ata_dev_set_mode() indicate error to the caller instead of disabling
port directly on failure.  Also, for consistency, ata_dev_present()
check is done in ata_set_mode() instead of ata_dev_set_mode().

This patch implements ata_dev_disable() which prints a warning message
and takes @dev offline.  Currently, this is done by explicitly
incrementing dev->class with case-by-case warning messages.  Giving
user clear indication when libata gives up will be more important as
libata will be doing more retries.

libata core is being changed to disallow port/device disable on lower
layers.  However, some LLDDs (sata_mv) directly disable port on
command failure.  This patch makes ata_exec_internal() check whether a
port got disabled after an internal command.  If it is, AC_ERR_SYSTEM
is added to err_mask and the port gets re-enabled.

As internal command failure results in device disable for drivers
which don't implement newer reset/EH callbacks, this change results in
no behavior change for single device per port controllers.  For
slave-possible LLDDs which disable port on command failure, (1) such
drivers don't exist currently, (2) issuing command to the other device
of once-disabled port shouldn't result in catastrophe even if such
driver exists.  So, this should be enough as a temporary measure.

	Once primary_router is set device stays in this mode.
	Issue an IP ASSIST command when no_router is set in route6.
	Device will be reset and thus will not longer run as a primary

With Au1xx0 Ethernet driver, TX bytes/packets always remain zero.  The
problem seems to be that when packet has been transmitted, the length word
in DMA buffer is zero.

The patch updates the TX stats when a buffer is fed to DMA.  The initial

2005.

The current code follows the spec but uses an overlong delay. This would
be great if the hardware did. Several vendors however forget the D7
pulldown. Fortunately 0xFF isnt a sane reset state so we can use it to

over a long time)

The problem is in ip_push_pending_frames(), which uses:

        if (!df) {
                __ip_select_ident(iph, &rt->u.dst, 0);
        } else {
                iph->id = htons(inet->id++);
        }

instead of ip_select_ident().

Right now I think the code is a nonsense. Most likely, I copied it from
old ip_build_xmit(), where it was really special, we had to decide
whether to generate unique ID when generating the first (well, the last)
fragment.

In ip_push_pending_frames() it does not make sense, it should use plain
ip_select_ident() instead.
