Subject: netifd: add defaultreqopts config option
X-Git-Tag: v18.06.0-rc1~1103
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=60e07ffec5d797ffae4417a8b8fc1854158e8faf

netifd: add defaultreqopts config option

By default udhcpc asks for a default list of options; the config option
defaultreqopts allows to tweak this behavior.
When set to 0 udhcpc will not ask for any options except for the options
specified in the reqopts config option.
