Subject: tools: hv: daemon setsockopt should use options macros
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f4685fa6d0427c3948a5120a9658fad7ae81facd;p=openwrt%2Fstaging%2Fblogic.git

tools: hv: daemon setsockopt should use options macros

HyperV daemon should use macros for option values when calling setsockopt.
Using specific numeric values instead of macros is confusing.
