This commit adds one step support to the phyter. When enabled, the
hardware does not provide time stamps for transmitted sync messages but
instead inserts the stamp into the outgoing packet.

This patch enables six external event channels and one periodic output.
One GPIO is reserved for synchronizing multiple PHYs. The assignment
of GPIO functions can be changed via a module parameter.
The code supports multiple simultaneous events by inducing a PTP clock
event for every channel marked in the PHY's extended status word.

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.

- 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.
Realtek's drivers use the same mask for the 816x and the fast ethernet
only 810x.

We check ether_type before registering the platform device in
arch/m68k/mac/config.c. Doing the same test again in the driver is
redundant so remove it.
Multiple probes should not happen since the conversion to platform devices,
so lose that test too.
Then macmace.c need not include macintosh.h, so remove that and irq.h and
include linux/interrupt.h explicitly.

The SMSC911X_USE_16BIT needs to be set when using 16-bit register
access. However, currently no flag is set if the device tree
doesn't specify 32-bit access, resulting in a BUG() and a non-
working driver when 16-bit register access is configured for
smsc911x in the DT.
This patch should set the SMSC911X_USE_16BIT flag in a manner
consistent with the documented DT bindings.

It seems that at least one PPC machine would occasionally give a (valid) 0 as
the return value from dma_map, this caused the ixgbe code to not work
correctly. A fix is pending in the PPC tree to not return 0 from dma map, but
we can also fix the driver to make sure we don't mess up in other arches as
well.
This patch is applicable to all current stable kernels.

When using MLPPP, the maximum size of a fragment is incorrectly
calculated with an offset of -2.
This patch reverses the changes in the patch found here:
http://marc.info/?l=linux-netdev&m=123541324010539&w=2
The value of hdrlen includes the size of both the 2-byte PPP protocol
field and the 2- or 4-byte multilink header (2+4=6 for long sequence
numbers, 2+2=4 for short sequence numbers). Section 2 of RFC1661 says
that the MRU that is negotiated (i.e., the MTU of the sending system)
includes only the PPP payload but not the protocol field, thus the
correct MTU should be the link's MTU minus the multilink header (mtu -
(hdrlen-2)).
The incorrect calculation causes Linux to fragment packets to a size two
bytes smaller than the allowed MTU. While not technically illegal, this
behaviour confounds MRU-tuning to avoid PPP-layer fragmentation.
