This adds 2 new states which both are used to toggle
the RX. These new states are required for usage
inside the link tuner thread, because the normal
RX toggling will stop the link tuner thread.
While it is possible that the link tuner thread itself
is the caller of the RX toggle (when using software
antenna diversity).

Fix 2 issues in antenna diversity selection.

1) the following statement will always return true.
	if ((rssi_curr - rssi_old) > -5 || (rssi_curr - rssi_old) < 5)
It is cleaner to check if the absolute value is smaller then 5.

2) Only enable software diversity when default antenna setup
indicates support for it. Don't select it when the hardware
does not indicate support for it...

This bug did bite at least one user, who did have to resort to rebooting
the system after an "ifconfig eth0 127.0.0.1" typo.

Deleting the address and adding a new is a less intrusive workaround.
But I still beleive this is a bug that should be fixed.  Some way or
another.

Another possibility would be to remove the scope mangling based on
address.  This will always be incomplete (are 127/8 the only address
space with host scope requirements?)

We set the scope to RT_SCOPE_HOST if an IPv4 interface is configured
with a loopback address (127/8).  The scope is never reset, and will
remain set to RT_SCOPE_HOST after changing the address. This patch
resets the scope if the address is changed again, to restore normal
functionality.

This behavior has been confirmed by Marvell with a SATA analyzer.
The Marvell port-multiplier apparently likes to see clean HOB
information when accessing PMP registers.

Since sata_mv uses PIO shadow register access, this doesn't happen
automatically, as it might in a more purely FIS-based driver (eg. ahci).

One way to fix this is to flag these commands with ATA_TFLAG_LBA48,
forcing libata to write out the HOB fields with known (zero) values.

Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir.

That's nice, but most SATA devices which need it will tell us about it
in their IDENTIFY PACKET response, as bit-15 of word-62 of the
returned data (as per ATA7, ATA8 specifications).

So for those which specify it, we should automatically use the DMADIR bit.
Otherwise, disc writing will fail by default on many SATA-ATAPI drives.

This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it
if atapi_dmadir is set or identify data indicates DMADIR is necessary.
atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting
DMADIR.

Original patch is from Mark Lord.

This counter is valuable to determine if the system is unable
to timely return buffers to the hardware and this counter starts
to increase well before the hardware starts to drop packets. If

hardware and will decrease the chance of hard drops.
