Subject: net: lwip: do not return CMD_RET_USAGE if no interface
X-Git-Url: http://git.dujemihanovic.xyz/img/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=b6691d0add999459393a19f0f02b66243ee2a4ae;p=u-boot.git

net: lwip: do not return CMD_RET_USAGE if no interface

If the dns command cannot find a network interface, we should return
CMD_RETFAIURE and not -1 (CMD_RET_USAGE).
