Subject: system-linux: Fix VTI ikey/okey on little endian systems
X-Git-Url: http://git.openwrt.org/?p=project%2Fnetifd.git;a=commitdiff_plain;h=e27e23f76437edc7871c03c8c92d69fbe52d30f5

system-linux: Fix VTI ikey/okey on little endian systems

The kernel expects the IFLA_VTI_IKEY and IFLA_VTI_OKEY netlink attributes to
be in network byte order, so ensure that the values are stored accordingly.
