separate PPS_out with time_valid.
    Disable transmitting packets when link is not up.

    command "ptp [mode] [port,df=0]" or "mode [mode] [port,df=0]"
  will set the ptp mode of port.
    Currently, if one port act as slave, its mode should be set
  after other ports.

    ip/ip get: print ip address of port 0&1
    ip set xx.xx.xx.xx [port]: set ip address of port, default port is 0

    sfp show: print sfp database of port 0&1
    sfp add sfp_pn dtx drx alpha [port]: set sfp database of port,
  default port is 0.

  before it acts as master.
    A known bug is sync cannot build after link reset.

    Make gensdbfs support the file order. sdb files should starts with xxfilename,
like 00wr-init. (In gensdbfs.c, I change the readdir() to scandir())
   Add two sdb files on 0x2e0000 to support the dualport's calibration and sfp
database. (db-calibration and db-sfp-database)
   Bug fix in shell/cmd_sfp.c.

   Now the one WR port function works well.

        tcpip tcp x , set the tcp server listen port
        tcpip udp txip x.x.x.x , set the udp tx destination ip addr.
        tcpip udp txport x , set the udp tx destination port, default
2000
        tcpip udp rxport x , set the udp rx destiniation port. default
(>256).
        tcpip udp txgw x.x.x.x , set the udp gateway, default x.x.x.1
        tcpip udp txsn x.x.x.x , set the subnet, default 255.255.255.0

There is no ns monotonic counter:(

This introduces "mode abscal", that forces a gm-lookalike mode in the
node, to send sync once per second. See "absolute calibration" document
by Peter Jansweijer from nikhef. The option is Kconfig'd, but on by
default.

While we also have atoi, our custom fromdec/fromhex are more similar
to strtol, and thus useful to parse "number.number" or such stuff.

And since I need to pass negative hex numbers in later commits, here
it is.

This was actually working anyways, because NULL pointers don't trap,
and the pointed-to char is currently 0x98, not a digit.

But I prefer to fix it before we do one of the following:
  - move to a new cpu that traps on null
  - use RAM at a different address than zeero
  - use "mvi r0, 0" instead of "xor r0,r0,r0" (would parse as 4).

It does not make sense when the init is stored in flash and the board has no
EEPROM. Otherwise, storage_init() calls mi2c_devprobe() if needed.
