With the legacy networking stack, it is possible to use USE_SERVERIP, SERVERIP and BOOTP_PREFER_SERVERIP Kconfg options to force use of a specific TFTP server ip.
Using the lwIP networking stack use of the 'tftpserverip' environment variable provide the closest equivalent functionality. Add USE_TFTPSERVERIP and TFTPSERVERIP Kconfig options that can be used to add the 'tftpserverip' environment variable to force use of a specific TFTP server ip.
