= NAME =
ov_transport_disconnect

= SYNOPSIS =
 * ov_transport_disconnect

= DESCRIPTION =
ov_transport_disconnect is an internal function used to release a connection
to the target.  It is called during the "post_test" phase (during cleanup) in order to
do any required operations to release the connection with the board.

It uses the $TRANPORT variable to select the correct method to use
to disconnect.

As with other "ov_" functions, it can be overridden in the board file for a board, to customize any operations required for disconnecting from a board.

This could be used for a number of things, including:

 * powering off a board
 * relinquishing a VPN connection to a remote lab
 * releasing a board reservation using an external board management system

= EXAMPLES =
none

= ENVIRONMENT and ARGUMENTS =
 * $TRANSPORT - specifies the type of transport used to communicate with the board.  This should be one of "ssh", "serial", "ttc".

= RETURN =
Returns non-zero on error
