When linking with particular PHY types (ex: copper PHY), the amount of
time it takes for the GLGEN_RSTAT_DEVSTATE to be set increases greatly,
which can lead to a timeout and failure to load the driver.

This patch fixes a problem where the ethtool identify adapter
functionality did not work for some copper PHY's.  Without this
patch, the blink led functionality fails on some parts.  This
patch adds PHY write code to blink led's on parts where this
functionality is contained in the PHY rather than the MAC.

In MFP mode particularly when we were setting the PF VSI in limited
promiscuous, the HW switch was still mirroring the outgoing packets
from other VSIs (VF/VMdq) onto the PF VSI.

With this new bit set, the mirroring doesn't happen any more and so
we are in limited promiscuous on the PF VSI in MFP which is similar
to defport.

An API check is not required, since this bit is reserved for FW API
version < 1.5

Also update copyright year in file headers.

With the latest firmware, statistics gathering can now be enabled and
disabled in the HW switch, so we need to add a parameter to allow the
driver to set it as desired.  At the same time, the L2 cloud filtering
parameter has been removed as it was never used.

Older drivers working with the newer firmware and newer drivers working
with older firmware will not run into problems with these bits as the
defaults are reasonable and there is no overlap in the bit definitions.
Also, newer drivers will be forced to update because of the change in
function call parameters, a reminder that the functionality exists.

Also update copyright year.

This patch fixes a problem where the NVMUpdate Tool, when using the PHY
NVM feature, gets bad data from the PHY because of contention on the
MDIO interface from get PHY capability calls from the driver during
regular operations.  The problem is fixed by adding a check if media
is available before calling get PHY capability function because that
bit is not set when device is in PHY interaction mode.

Add a module_types variable to the link_info struct to save the module
information from get_phy_capabilities. This information can be used to
determine which speeds the module supports.

Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.

The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.

Use the new variable in ethtool to differentiate between a 10G/1G dual
speed fiber module and a 10G only module.

Previously, the driver could call this function and have only true/false
returned, but false could mean multiple things like failure to read
or link was down. This change allows the caller to get all return values
in the call chain bubbled back to the source, which keeps information about
failures from being lost.

Also, in some unlikely scenarios, the firmware can become slow to respond
to admin queue (AQ) queries for link state.  Should the AQ time out,
the driver can detect the state and avoid a link change when there
may have been none.
