In function fec_enet_mii_init(), it uses non-zero pdev->id as part
of the condition to check the second fec instance (fec1).  This works
before the driver supports device tree probe.  But in case of device
tree probe, pdev->id is -1 which is also non-zero, so the logic becomes
broken when device tree probe gets supported.

The patch change the logic to check "pdev->id > 0" as the part of the
condition for identifying fec1.

FEC can work without a phy reset on some platforms, which means not
very platform necessarily have a phy-reset gpio encoded in device tree.
Even on the platforms that have the gpio, FEC can work without
resetting phy for some cases, e.g. boot loader has done that.

So it makes more sense to have the phy-reset-gpio request failure as
a debug message rather than a warning, and get fec_reset_phy() return
void since the caller does not check the return anyway.

Use the PCI device flag indicating if a VF is assigned to a guest VM
to guard against destroying VFs upon driver removal.  Implement
additional feature to detect if VFs already exist when the driver

Device drivers that create and destroy SR-IOV virtual functions via
calls to pci_enable_sriov() and pci_disable_sriov can cause catastrophic
failures if they attempt to destroy VFs while they are assigned to
guest virtual machines.  By adding a flag for use by the KVM module
to indicate that a device is assigned a device driver can check that
flag and avoid destroying VFs while they are assigned and avoid system
failures.

- fix features : jumbo frames and checksumming can not be used at the
  same time.

- introduce hw_jumbo_{enable / disable} helpers. Their content has been
  creatively extracted from Realtek's own drivers. As an illustration,
  it would be nice to know how/if the MaxTxPacketSize register operates
  when the device can work with a 9k jumbo frame as its documentation
  (8168c) can not be applied beyond ~7k.

- rtl_tx_performance_tweak is moved forward. No change.

8168d and above allow jumbo frames beyond 8k. Bump the received
packet length check before enabling jumbo frames on these chipsets.

Frame length indication covers bits 0..13 of the first Rx descriptor
32 bits for the 8169 and 8168. I only have authoritative documentation
for the allowed use of the extra (13) bit with the 8169 and 8168c.

only 810x.

xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the
following was true:

 - The caller knows how many bytes of output to expect and only provides
   that much output space.

 - When the last output bytes are decoded, the caller-provided input
   buffer ends right before the LZMA2 end of payload marker.  So LZMA2
   won't provide more output anymore, but it won't know it yet and thus
   won't return XZ_STREAM_END yet.

 - A BCJ filter is in use and it hasn't left any unfiltered bytes in the
   temp buffer.  This can happen with any BCJ filter, but in practice
   it's more likely with filters other than the x86 BCJ.

This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where
Squashfs thinks that a valid file system is corrupt.

This also fixes a similar bug in single-call mode where the uncompressed
size of a block using BCJ + LZMA2 was 0 bytes and caller provided no
output space.  Many empty .xz files don't contain any blocks and thus
don't trigger this bug.

This also tweaks a closely related detail: xz_dec_bcj_run() could call
xz_dec_lzma2_run() to decode into temp buffer when it was known to be
useless.  This was harmless although it wasted a minuscule number of CPU
cycles.
