/*******************************************************************************
* mvEthProtWinSet - Set access protection of Ethernet to target window.
*
* DESCRIPTION:
* Each Ethernet port can be configured with access attributes for each
* of the Ethenret to target windows (address decode windows). This
* function sets access attributes to a given window for the given channel.
*
* INPUTS:
* ethPort - ETH channel number. See MV_ETH_CHANNEL enumerator.
* winNum - IETH to target address decode window number.
* access - IETH access rights. See MV_ACCESS_RIGHTS enumerator.
*
* OUTPUT:
* None.
*
* RETURN:
* MV_ERROR in case window number is invalid or access right reserved.
*
