82599 has a FW running that helps manage the internal SFI PHY. There are
also a number of pre-production samples of these SFI-based devices in the
field. This patch adds a check to look for the firmware running on all
SFP+ based adapters, and displays a warning to the system log if a
pre-production adapter is identified. The driver will continue loading
though, with no functional degradation.
Also remove an old function prototype from ixgbe_82599.c that isn't being
used.

This patch adds the functions for ixgbe to initialize Flow Director. It
also has the function APIs to add Flow Director filters from the base
driver. This also includes ATR, Application Targeted Routing, which is a
feature set of Flow Director. This is the hash-based mechanism to
automatically identify flows and add filters based on the hash, and direct
the Rx of that flow back to that same CPU.

Flow Director is a Rx filter mechanism designed to match Rx flows back to
the same CPU that the flow's Tx occurred from. This patch adds the first
piece, the defines for the hardware registers, to enable this feature in
82599 hardware.

This patch moves the tx cleanup processing out of the MSI-X interrupt
processing and gives it it's own napi routine. This allows the driver to
process TX cleanup in a polling context instead of in an interrupt context
which prevents TX from starving RX.

The v_idx value was being used as both a bitmask and an index. This change
makes it so that the q_vector contains the index and allows for much of the
code to be simplified since disabling a q_vector involves only clearing one
bit in the interrupt bitmask.

This patch changes the driver so that it uses rx_buffer_info->dma to
determine if it needs to unmap the page instead of sh_info->nr_frags. This
helps to prevent a cache line miss when receiving small packets as the
rx_buffer_info data should already be in the cache.

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.
