[ Upstream commitbbe4b41259] net.ipv4.nexthop_compat_mode was added when nexthop objects were added to provide the view of nexthop objects through the usual lens of the route UAPI. As nexthop objects evolved, the information provided through this lens became incomplete. For example, details of resilient nexthop groups are obviously omitted. Now that 16-bit nexthop group weights are a thing, the 8-bit UAPI cannot convey the >8-bit weight accurately. Instead of inventing workarounds for an obsolete interface, just document the expectations of inaccuracy.
