Subject: dns: move dns_add_nameserver() to dhcpc
X-Git-Tag: 1.1_Public_Release~614^2~79
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=db891df81abc0dfe512f501f193f6ad3ffa470da;p=rtos%2Ftinyara.git

dns: move dns_add_nameserver() to dhcpc

This commit is to change the place dns_add_nameserver function

when CONFIG_NETDB_DNSSERVER_BY_DHCP enabled, dns server IP address
is configured by using received dhcp message
without using ifconfig command, dns server can not be configured
so that to prevent the dns server configuration problem
we've changed the place of dns_add_nameserver to dhcpc
