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

    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.

  Now it works as below:
    1. default udp tx dst mac is the gateway of node's ip.
    2. It will send arp request after getting the udp tx dst ip.
    3. It stops sending arp request after getting the udp tx dst mac addr.

the configuration written to WB registers using commands in the
wr-streamers tools is used to override the default configuration
set with generics. one can enable/disable this overriding, meaning
that the original default configuration can be effective again.
this functions enables/disables overriding.

- for the qtag configuration to be effective, an appropriate override
  bit needs to be set, this was missing, fixed
- the function was first enabling the qtag-ing and then configuring it,
  this is not a good behavior, it is better to be enabled later (when
  the configuration is set, otherwise it will start sending frames
  tagged with some random config), fixed

these commands are not critical for the current release, the fix will take
some time, the codebase is good. let's make it work later

- new command "ls" (leapsecond to overwrite the default value
- implement get_set_tx_local_mac, get_set_tx_remote_mac
  get_set_rx_ethertype get_set_rx_local_mac, get_set_rx_remote_mac,
