The following patch moves the handling of the I2C MUX (which is only
used for x550em SFP+ devices) out of the ixgbe_x540.c file and
into the ixgbe_x550.c file where it belongs.

The init flow is simplified. We no longer wait for the PHY FW init
complete bit to be set as this bit is only set once by the PHY at power
on and then cleared on the first read. So only the first instance of
running SW (or possibly MAC FW) needs to initialize the PHY.
The PHY initialization has been simplified and now only requires that
the PHY FW be "un-stalled". SW no longer needs to put the PHY in
low-power mode or enable the transceiver.

This patch adds SFP+ dual-speed support.
82599 fiber link code was moved from ixgbe_82599.c to ixgbe_commom.c
for use by X550em, and the API was updated to support the common code
usage. SFP MAC link code is added to x550em.

The FEC (Forward Error Correction) feature can improve BER (Bit Error Rate)
but uses more power to do so. It also cannot be used with
EEE (Energy Efficient Ethernet).
EEE is an important feature, and we have no known BER issues, so FEC
is not needed.

The I2C mux control relies on the SDP setting in the ESDP register
so it is necessary to restore the value after a MAC reset. So,
put the code in a function so it can be used in more than one place.

The driver now needs to issue a firmware command to inform the
firmware that a driver is coming up. This prevents the possibility
of the firmware and the driver configuring the PHY at the same
time. Upon completion of the command, the firmware will no longer
be configuring the PHY.

A retry count of 10 is likely to run into problems on X550 devices
that have to detect and reset unresponsive CS4227 devices. So,
reduce the I2C retry count to 3 for X550 and above. This should
avoid any possible regressions in existing devices.

SGE addresses are 64 bit integers, converting them to pointers must be done

Negotiate the virtio ring size. The host may allow for very large
rings but application may only want a smaller ring.
Conversely, if the number of descriptors requested exceeds the virtio
host queue size, then just silently use the smaller host size.
This fixes issues with virtio in non-QEMU envirionments.
For example Google Compute Engine allows up to 16K elements
in ring.

Change the features from bit mask to bit number. This allows the
DPDK driver to use the definitions from Linux (yes the header
files already use a license compatiable with DPDK). This makes DPDK
driver handle future feature bit changes.

Instead just have a new define with the list of feature bits implemented.
