In rare instances, memory errors have been detected in the internal packet
buffer memory on I217/I218 when stressed under certain environmental
conditions.  Enable Error Correcting Code (ECC) in hardware to catch both
correctable and uncorrectable errors.  Correctable errors will be handled
by the hardware.  Uncorrectable errors in the packet buffer will cause the
packet to be received with an error indication in the buffer descriptor
causing the packet to be discarded.  If the uncorrectable error is in the
descriptor itself, the hardware will stop and interrupt the driver
indicating the error.  The driver will then reset the hardware in order to
clear the error and restart.

Both types of errors will be accounted for in statistics counters.

This change is meant to inline the Rx PTP descriptor handling.  The main
motivation is to avoid unnecessary jumps into function calls that we then
immediately exit because we are not performing timestamps.

The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU
utilization in my performance runs to 0%, and the only value tested is the Rx
descriptor which should already be warm in the cache if not stored in a
register.

This patch copies the igb implementation of Tx timestamps, which uses a work
item to poll for the Tx timestamp. In addition it adds a timeout value of 15
seconds, after which it will stop polling.

This is necessary due to an issue with the descriptor being marked done before
the Tx timestamp event has occurred. These two events don't correlate, so using
the done bit on the descriptor as indication that the timestamp must already
have been taken leads to potentially dropped Tx timestamps (especially under
heavy packet load)

This patch removes ixgbe_ptp_match, and the corresponding packet filtering from
ixgbe driver. This code was previously causing some issues within the hotpath of
the driver. However the code also provided a check against possible frozen Rx
timestamp due to dropped packets when the Rx ring is full. This patch provides a
replacement solution based on the watchdog.

To this end, whenever a packet consumes the Rx timestamp it stores the jiffy
value in the rx_ring structure. Watchdog updates its own jiffy timer whenever
there is no valid timestamp in the registers.

If watchdog detects a valid timestamp in the registers, (meaning that no Rx
packet has consumed it yet) it will check which time is most recent, the last
time in the watchdog, or any time in the rx_rings. If the most recent "event"
was more than 5seconds ago, it will flush the Rx timestamp and print a warning
message to the syslog.

This patch updates the filters for ethtool's get_ts_info to return support for

behind this change is due to reasoning that we do in fact support the

upscaled version). In this way we can remain consistent over which filters are
supported via the get_ts_info ioctl and which filters are in practice actually
supported.

This patch cleans up the ethtool diagnostics test by ensuring that the tests
work properly regardless of what state the adapter was in. The SRIOV VF check is
done at the beginning, forgoing the link test. The if_running -> dev_close is
moved before the link test, as well as a call to enable the Tx laser. This
ensures that the link test will return valid results even when adapter was
previously down. Also, a call to disable the Tx laser is added if the device
was down before the start. This ensures consistent behavior of the Tx laser
before and after the diagnostic checks. The end result is consistent behavior
regardless of device state.

When posting a message on the bulletin board, the PF calculates crc
over the message and places the result in the message. When the VF
samples the Bulletin Board it copies the message aside and validates
this crc. The length of the message is crucial here and must be the
same in both parties. Since the PF is running in the Hypervisor and
the VF is running in a Vm, they can possibly be of different versions.
As the Bulletin Board is designed to grow forward in future versions,
in the VF the length must not be the size of the message structure
but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ.  During chip reset,
for example, cnic will stop servicing IRQs after it has shutdown the
cnic hardware resources.  However, the shared IRQ is still active as
bnx2x needs to finish the reset.  There is a window when bnx2x does
not know that cnic is no longer handling IRQ and things don't always
work properly.

Add a flag to tell bnx2x that cnic is handling IRQ.  The flag is set
before the first cnic IRQ is expected and cleared when no more cnic
IRQs are expected, so there should be no race conditions.
