This program interacts with Omnia MCU over I2C bus. It displays version
of the MCU firmware - both bootloader and application parts (which are
the git hashes compiled into the images) and flash application image
to the MCU EEPROM.

The sendbeacon program sends "beacon" to stop boot of Marvell Armada 385
so it waits for kwboot to load up U-Boot.

Fix cron timetable and make comparing of snapshots just an optional feature run
only once a week.

Basically autodetection of BTRFS based system depended on it being mounted as
root which is not a case in rescue system.

• Don't restart resolver every time, the name in ps is different than
  the service name.
• Resolver is mandatory service (unbound wasn't, there could be a
  different resolver, but some resolver is needed now).
• Parameter placement with uci.

Add support of SGMII SFP modules to the sfpswitch daemon.
The daemon has to read I2C EEPROM in the SFP module to determine module
type. If the module seems to be 1000BASE-T, then set it to SGMII mode.

Refacotr sfpswitch script in order to reuse code.
Add support for better --oneshot (set SFP, do not daemonize)
Add support for --resetled (Reset LED status, do not touch SFP mode,
do not daemonize).

Add LED indication to the sfpswitch daemon for Omnia.
The WAN LED has to be driven by software when SFP is inserted.
LED lights when the LOS and FLT signals are inactive.
The DIS signal has to be set to inactive.

The sfpswitch daemon has to bring the NIC down for sure before
calling network restart.

Add safety timeout to be sure the network down/up happens after
the switch is comitted to the kernel.
