Subject: [PATCH] nl80211: fix monitor flags
Date: Wed, 15 Oct 2008 11:54:04 +0200 [thread overview]
Message-ID: <1224064444.27537.2.camel@johannes.berg> (raw)
NLA_NESTED attributes cannot be empty, but we want to be able to
specify "no flags" (empty attribute) vs. "no change" (no attribute).
Therefore, remove the NLA_NESTED policy so it can work as an empty
attribute.
I guess I should have used a u32 for these flags instead, but we're
stuck with it now. Haven't noticed earlier because of a bug in iw...
