Should not run HW clock overflow check if HW clock is not supported. Also, since
this watchdog is the only customer of service_task, no need to start it in that case.

Add reference counting to the driver MAC registeration code. This would
be needed for cases where a mac is registered from more than once, e.g
when both the host and the VM driver register the same mac, the host
for mac spoof protection purposes and the VM for its regular needs.

This patch add struct mlx4_vport_state where all the parameters related
to management of VFs port (virtual ports of the NIC eswitch) are kept.
The driver keeps an administrative and operational copy of the settings.
The current administrative copy becomes operational on the event of probing
a VF either on a VM or on the host.

From: Rony Efraim <ronye@mellanox.com>
Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport
is considered to be in VST mode. In this mode, the PPF driver configures
Ethernet QPs created by this VF to use this vlan id and priority. Currently
RoCE isn't supported on that mode.
The special values of VID=4095 or VID=0,UP=0 are considered as VGT.
