[OpenWrt-Devel] [netifd][PATCH v3] proto-shell: add hostname validation check for netifd dhcp script

[tymon.huang]

This patch can fix the issue that luci web shows '?' sign when WAN port work on DHCP-client mode without
setting hostname. After adding the hostname check, the udhcpc can work with '-H' parameter correctly and
send hostname to dhcp server.
