Enable ALDPS function to save power when link down. Note that the
feature should be set after the other PHY settings. And the firmware
is necessary. Don't enable it without loading the firmware.
None of the firmware-free chipsets support ALDPS. Neither do the
RTL8168d/8111d.
For 8136 series, make sure the ALDPS is disabled before loading the
firmware. For 8168 series, the ALDPS would be disabled automatically
when loading firmware. You must not disable it directly.

FW flashing code, even though it works correctly, makes some hidden

This is a HW requirement. Although a buffer as short as 1 byte is allowed,
the total length of packet before, padding and CRC insertion, must be at
least 17 bytes. So pad all small packets manually up to 17 bytes before
delivering them to HW.

We were not correctly freeing the temporary rings on error in
ixgbe_set_ring_param. In order to correct this I am unwinding a number of
changes that were made in order to get things back to the original working
form with modification for the current ring layouts.
This approach has multiple advantages including a smaller memory footprint,
and the fact that the interface is stopped while we are allocating the rings
meaning that there is less potential for some sort of memory corruption on the
ring.
The only disadvantage I see with this approach is that on a Rx allocation
failure we will report an error and only update the Tx rings. However the
adapter should be fully functional in this state and the likelihood of such
an error is very low. In addition it is not unreasonable to expect the
user to need to recheck the ring configuration should they experience an
error setting the ring sizes.

This patch modifies when and where PTP registers and data are set. Previously
a work-around was used inside cyclecounter_start in order to reset some of the
time registers. This patch creates a new ixgbe_ptp_reset specifically for this
purpose. The cyclecounter configuration has trimmed down to only modify what
is necessary. Due to hardware conditions after probe and before open, PTP init
has now moved into the ixgbe_open call. This allows the ptp device name in the
sysfs to be the ethernet device name instead of the MAC address.
The cyclecounter check flag is renamed to PTP_ENABLED and is used to prevent
PTP init from happening when PTP has not been enabled.

This change adds support for IPv6 and UDP to ixgbe_get_headlen. The
advantage to this is that we can now handle ipv4/UDP, ipv6/TCP, and
ipv6/UDP with a single memcpy instead of having to do them in multiple
pskb_may_pull calls.
A quick bit of testing shows that we increase throughput for a single
session of netperf from 8800Mpbs to about 9300Mpbs in the case of ipv6/TCP.
As such overall ipv6 performance should improve with this change.
