		If this option is selected, the NSH will call into platform-specific

		Where buffer is the location to return the MOTD and buflen is the

		by NSH_FILEIOSIZE.  An appopriate location for the
		implementation of platform_motd would be within apps/platform/<board>.

		One newline will be inserted after the platform-supplied message.

			set FOO XYZ
			set BAR 123
			set FOOBAR ABC_${FOO}_${BAR}

		would set the environment variable FOO to XYZ, BAR to 123 and FOOBAR

		If this option is selected, then NSH will only initialize the local

		addresses as needed.  More importantly, it will not do the following:

		- It will not bring the network up.  That can be done later with the
		  NSH ifup command.
		- It will not associate any wireless devices to an access point.
		- It will not attempt to obtain an IP address if DHCPC is selected.
		  This may be done later from the NSH command line with the
		  apps/system/dhcpc 'renew' command.
		- It will not start the NTPC daemon.  This may be done later from
		  the NSH command line with the apps/system/ntpc 'ntpcstart' command.

		This option permits you to divide the network configuration into two
		parts:  The local configuration of the network device and the dynamic

		available access points and associate the wireless driver with an

		NSH is brought up through a series of sequential initialization
		steps.  This includes networking. If the network is available on
		reset, then there is really no issue.  Negotiating the link will
		take only a second or so and the delay to the NSH prompt is
		normally acceptable.

		But if there is no network connected, then the start-up delay can
		be very long depending upon things like the particular PHY, driver
		timeout delay times and number of retries.  A failed negotiation
		can potentially take a very long time, perhaps as much as a
		minute... Long enough that you might think that the board would
		never come up!

		One solution is enabled by this option.  If NSH_NETINIT_THREAD
		is selected, the network bring-up will occur in parallel with
		NSH on a separate thread.  In this case, the NSH prompt will occur
		immediately with the network becoming available some time later (if
		if all).  This thread will terminate once it successfully initializes
		the network

		NOTES:  If no network is connected, the network bring-up will fail
		and the network initialization thread will simply exit.  There are
		no retries and no mechanism to know if the network initialization
		was successful.  Furthermore, there is currently no support for
		detecting loss of network connection.  Lots of things to do!

		If this option is selected, however, then the network initialization

		the event that the network goes down (for example, if a cable is
