Hello. I'm developing an application that uses libnl to get some wireless stats and I use iw code as an example. I noticed that not all parameters are added to nla_policy. For example, NL80211_STA_INFO_CONNECTED_TIME (https://git.kernel.org/pub/scm/linux/kernel/git/jberg/iw.git/commit/?id=087d778f6f82346debfd275ddbb8f646f9a1a167) is parsed, but absent from stats_policy. The question is whether it is done accidentally or deliberately? Is there some hidden logic not to add attributes to policy? And then why to use policy at all if some attributes are not checked anyway? Thanks in advance, Sergey.
