This patch series is bugfix for the hang-up issue in Netsec driver.

Some linux distributions such as Ubuntu power down the ethernet phy
in reboot. In this case, Netsec initialization fails and
system hungs.

This patch series add the robust netsec initialization,
set ethernet phy as loopback mode to expect stable RXCLK,
and wait for media link up.

The disadvantage of this patch series is that user has to wait
several seconds until netsec driver gives up ethernet link-up
if the ethernet cable is not connected.

Changes since v2:
  - use From: tag instead of Signed-off-by:

Changes since v1:
  - modified wrong indent
  - updated order of new parameter
  - updated comment
  - removed unrelated whitespace changes
