This commit makes use of the AHCI_HFLAG_YES_ALPM flag to prevent
the driver from writing to the read-only Host Capability register.
It also sets the AHCI_HFLAG_NO_WRITE_TO_RO flag to prevent the AHCI
library from writing to read-only registers.

While most hardware will simply ignore a write to a read-only register,
some hardware will signal an abort if this occurs.
This commit introduces the flag AHCI_HFLAG_NO_WRITE_TO_RO to prevent the
AHCI library from attempting to write to the HOST_CAP, HOST_CAP2, and
HOST_PORTS_IMPL registers which may be read-only.

Some hardware is capable of supporting Aggresive Link Power Management
even though it is not indicated by the Host Capability register.
This commit adds the AHCI_HFLAG_YES_ALPM flag to the AHCI library to
allow indication of this quirk when the Host Capability register is
Read Only and therefore cannot be changed.

This adds a driver for the Faraday Technology FTIDE010
PATA IP block.
When used with the Storlink/Storm/Cortina Systems Gemini
SoC, the PATA interface is accompanied by a PATA<->SATA
bridge, so while the device appear as a PATA controller,
it attaches physically to SATA disks, and also has a
designated memory area with registers to set up the bridge.
The Gemini SATA bridge is separated into its own driver
file to make things modular and make it possible to reuse
the PATA driver as stand-alone on other systems than the
Gemini.

This adds device tree bindings for the Faraday Technology
FTIDE010 found in the Storlink/Storm/Cortina Systems Gemini SoC.
I am not 100% sure that this part is from Faraday Technology but
a lot points in that direction:
- A later IDE interface called FTIDE020 exist and share some
properties.
- The SATA bridge has the same Built In Self Test (BIST) that the
Faraday FTSATA100 seems to have, and it has version number 0100
in the device ID register, so this is very likely a FTSATA100
bundled with the FTIDE010.

When running LDom binding/unbinding test, kernel may panic
in ldmvsw_open(). It is more likely that because we're removing
the ldc connection before unregistering the netdev in vsw_port_remove(),
we set up a window of time where one process could be removing the
device while another trying to UP the device. This also sometimes causes
vio handshake error due to opening a device without closing it completely.
We should unregister the netdev before we disable the "hardware".

Every address gets added with TENTATIVE flag even for the addresses with
IFA_F_NODAD flag and dad-work is scheduled for them. During this DAD process
we realize it's an address with NODAD and complete the process without
sending any probe. However the TENTATIVE flags stays on the
address for sometime enough to cause misinterpretation when we receive a NS.
While processing NS, if the address has TENTATIVE flag, we mark it DADFAILED
and endup with an address that was originally configured as NODAD with
DADFAILED.
We can't avoid scheduling dad_work for addresses with NODAD but we can
avoid adding TENTATIVE flag to avoid this racy situation.

Macvlan always turns on offload features that have sofware
fallback (NETIF_GSO_SOFTWARE). This allows much higher guest-guest
communications over macvtap.
However, macvtap does not turn on these features for vlan tagged traffic.
As a result, depending on the HW that mactap is configured on, the
performance of guest-guest communication over a vlan is very
inconsistent. If the HW supports TSO/UFO over vlans, then the
performance will be fine. If not, the the performance will suffer
greatly since the VM may continue using TSO/UFO, and will force the host
segment the traffic and possibly overlow the macvtap queue.
This patch adds the always on offloads to vlan_features. This
makes sure that any vlan tagged traffic between 2 guest will not
be segmented needlessly.
