virtio: do not report link state feature unless available
If host does not support virtio link state (like current DPDK vhost)
then don't set the flag. This keeps applications from incorrectly
assuming that link state is available when it is not. It also
avoids useless "guess what works in the config".

The new logic will allow set of a vlan if it is zero, automatically

fm10k/base: scale interrupt on PCIe link speed
Red Rock Canyon's interrupt throttle timers are based on the PCIe link
speed. Because of this, the value being programmed into the ITR
registers must be scaled.
For the PF, this is as simple as reading the PCIe link speed and storing
the result. However, in the case of SR-IOV, the VF's interrupt throttle
timers are based on the link speed of the PF. However, the VF is unable
to get the link speed information from its configuration space, so the
PF must inform it of what scale to use.
Rather than passing this scale via mailbox message, we take advantage of
unused bits in the TDLEN register to pass the scale. It is the
responsibility of the PF to program this for the VF while setting up the
VF queues and the responsibility of the VF to get the information
accordingly. This is preferable because it allows the VF to set up the
interrupts properly during initialization and matches how the MAC
address is passed in the TDBAL/TDBAH registers.
A VF unload followed by a reload incorrectly left this value as 0.
If the VF driver blindly trusted this value it could cause a divide by
zero failure.
Fix this by having stop_hw_vf reset the ITR scale as the device goes
down, similar to the way we handle the MAC address.
To prevent divide-by-zero issues, ensure that we always have an ITR
scale. Default to Gen3 scaling if we don't know the speed. Also ensure
the VF checks the register value and ensures we use Gen3 if we are
provided a zero value.
