In case of MFP mode the driver was returning incorrect number of TCs
for partitions that are not enabled for iSCSI. Though the driver does
not configure these TCs in the Tx scheduler for the NIC partitions;
it does use this map to setup the queue mappings.

This patch fixes this and keeps all the NIC partitions to the default
PF TC i.e. TC0.

With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.

Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.

Cleanup the port forwarding state transitions for the cases when the port
joins or leaves a bridge, or is brought admin UP or DOWN.  When port is
bridged, we can rely on bridge driver putting port in correct state using
STP callback into port driver, regardless if bridge is enabled for STP or not.
When port is not bridged, we can reuse some of the STP code to enabled or
disable forwarding depending on UP or DOWN.

Tested by trying all the transitions from bridge/not bridge, and UP/DOWN, and
verifying port is in the correct forwarding state after each transition.

Add support for bridge offload ndo_ops getlink and setlink to
enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
The support is only enabled in case of a PF VSI and not available for
any other VSI type.

By default the i40e driver inserts a bridge as part of the bring-up
when a FDIR type VSI and/or a FCoE VSI is created. This bridge is
created in VEB mode by default i.e. after creating the bridge using
"Add VEB" AQ command the loopback for the PF's default VSI is enabled.

The patch adds capability where all the VSIs created as downlink to
the bridge inherits the loopback property and enables loopback only
if the uplink bridge is operating in VEB mode.
Hence, there is no need to explicitly enable loopback as part of
allocating resources for SR-IOV VFs and call to do that has been
removed.

In case a user-request is made either via "bridge" utility or using
the bridge netlink interface that requires to change the hardware
bridge mode then that would require a PF reset and rebuild of the
switch hierarchy.

We export three controls:
	min_bw - Can take a value from 0 to 100 inclusive
	max_bw - Can take a value from 1 to 100 inclusive
	commit - A write-only control that accepts only a value of 1 and will
		cause the BW settings to be permanently committed to NVM so
		that they are persistent across power cycles and system
		resets

The BW values are relative and are expressed as percentages.  For more
information on the interpretation of the BW settings see the Dell

Add a requested speed variable to the link_status struct to store the
last speeds we requested from the firmware (the speeds the FW will be
advertising with if autoneg is enabled).

Use the advertised speed settings in get_settings in ethtool now that
we have it.  Also set the requested speed settings in set_settings in
ethtool as they are requested and initialize them in probe based on what
the firmware remembers as the last requested speeds.

To accommodate some longer lines in this new code, and improve
readability I have added two functions i40e_get_settings_link_up
and i40e_get_settings_link_down which get_settings now calls first.
It then does all of the settings that happen regardless of link
state. Some PHY types that supported the same settings were also combined.
