d6b2a38a92 modules/mqnic: Fix link status monitoring, initialize stored link status on start to "down" 
Assume that the hardware link status is "down" when a netdev is brought "up"
administratively ("ip link set dev ... up"). This way a change of link status is
always occuring, in case hardware link status is indeed still "up" at that point
in time.

Otherwise bringing a netdev administratively "down" and "up" again, while the
hardware was "up" before and stays "up" during the administrative "down" period,
results in no netif_carrier_on() being called, because struct
mqnic_priv::link_status does not change.

0d2e794b74 modules/mqnic: Add link status monitoring 
This solution is based on the assumption that, if there are multiple
(mqnic-)ports per (mqnic-)interface, the single netdev, which is currently
associated with one (mqnic-)interface, is assumed to be up, when all ports' TX
and RX status bits are asserted. As soon as one of these bits is deasserted for
any of the involved ports the netdev is assumed to be down.

Module parameter "link_status_poll" specifies the polling interval in
milliseconds. Setting it to 0, disables any form of monitoring. By default we
check once per second, which is a totally arbitrary choice - no special
reasoning.
