There are some possible discrepancies between data shown by the driver
with the actual NIC/FW state.

First 4 patches address problem with link state correctness. In some
scenarios FW may not be able to notify the driver about link change.
Along with fix, refactor the whole approach to LSE (Link Status Events)
enablement. As there's no any reasonable argument for disabling LSE
during driver life cycle, make them constantly enabled.

5th and 6th patches address problem occurring when FW changes MAC address.
There's no any kind of notify/event accompanying that change. Therefore let the
driver to poll for the new address.

Jedrzej Jagielski (6):
  ixgbe: E610: init Link Status Events mask just once
  ixgbe: E610: prevent from disabling LSE
  ixgbe: E610: do not disable LSE on driver down/remove
  ixgbe: E610: re-enable LSE unconditionally
  ixgbe: E610: add MAC address runtime refresh
  ixgbe: take rtnl lock before ixgbe_reset() is called
