This change fixes several issues found in ntuple filtering while I was
doing the ATR refactor.
Specifically I updated the masks to work correctly with the latest version
of ethtool, I cleaned up the exception handling and added detailed error
output when a filter is rejected, and corrected several bits that were set
incorrectly in ixgbe_type.h.
The previous version of this patch included a printk that was left over from
me fixing the filter setup. This patch does not include that printk.

This change adds a compressed input type for atr signature hash
computation. It also drops the use of the set functions when setting up
the ATR input since we can then directly setup the hash input as two dwords
that can be stored and passed as registers.
With these changes the cost of computing the has is low enough that we can
perform a hash computation on each TCP SYN flagged packet allowing us to
drop the number of flow director misses considerably in tests such as
netperf TCP_CRR.

This change cleans up the layout of the flow director data, and the
algorithm used to calculate the hash resulting in a 35x / 3500% performance
increase versus the old flow director hash computation. The overall effect
is only a 1% increase in transactions per second though due to the fact
that only 1 packet in 20 are actually hashed upon.

Add support for the anti-spoofing feature in the HW. Packets from
VF devices with spoofed MAC addresses or VLAN tags will be blocked
and a counter incremented. During the watchdog timer the spoofed
packet dropped counter is read and if it is non-zero then a warning

This patch helps prevent FW/SW semaphore collision from leading
to link establishment failure. The collision might mess up the
PHY registers so we reset the PHY. However there are SFI/KR areas
in the PHY that are not reset with a Reset_AN so we need to change
LMS to reset it. Also wait until AN state machine is AN_GOOD

The ethtool utility does not set masks for flow parameters that are
not specified, so if both value and mask are 0 then this must be
treated as equivalent to a mask with all bits set. Currently that is
done in the only driver that implements RX n-tuple filtering, ixgbe.
Move it to the ethtool core.

This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.

Fix 82599 link issues during driver load and unload test using multi-speed
10G & 1G fiber modules. When connected back to back sometime 82599 multispeed
fiber modules would link at 1G speed instead of 10G highest speed, due to a
race condition in autotry process involving Tx laser flapping. Move autotry
autoneg-37 tx laser flapping process from multispeed module init setup
to driver unload. This will alert the link partner to restart its
autotry process when it tries to establish the link with the link partner

The PF Reset Done bit should not be set in the extended control register
until the PF has actually completed the bring up process. It is a mis-
interpretation of the purpose of this bit to assume it should be set
when the physical reset of the device is done. Instead it should be used
to indicate to the VFs when the PF is ready to provide them with required
services. This is not until after the PF is finished coming up and ready
to process mailbox events.

without any cable and reconnecting it to 1G partner
In 82599 multi speed fiber case when driver is loaded without any
cable and reconnecting the cable with a 1G partner does not bring
up the link in 1Gb mode. When there is no link we first setup the link
at 10G & 1G and then try to re-establish the link at highest speed 10G
and thereby changing autoneg_advertised value to highest speed 10G.
After connecting back the cable to a 1G link partner we never try 1G
as autoneg advertised value is changed to link at 10G only. The
following patch fixes the issue by properly initializing the
autoneg_advertised value just before exiting from link setup routine.

82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some
scenarios can cause the autotry mechanism to not negotiate link properly.
What needs to happen is the driver must flap the Tx laser to induce an Rx
Loss of Signal on the link partner. This will restart the autotry
mechanism to get link into a known state. The software definable pin (SDP)
3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the
Rx LOS we require.

When reprogramming the 82599 analog PHY to either SFI optical or Direct
Attach Twinax, we need to restart the DSP in the PHY. The current method
can cause contention with our FW which is managing PHY state, and will
cause unexpected link flaps. This patch fixes the DSP restart by issuing
an AN_RESTART in the MAC, which will properly propagate the DSP restart to
the PHY. This ensures we don't collide with the FW.

Device ID 0x10d8 is the default silicon device ID for 82599. However, the
device will not be functional without an EEPROM, so we want to prevent the
driver from loading on the device. Otherwise, the driver will load, but no
PHY setup or PCIe setup will occur, causing the device to be unusable. To
prevent users from encountering this, just remove the device ID.
