From b1f93314bfc4d5753391616735f6b8df96db901d Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 4 Feb 2011 19:20:08 +0100 Subject: mac80211: do not send duplicate data frames to the cooked monitor interface I can't think of a valid use case for this aside from debugging (which can also be done with a real monitor interface), and dropping these frames saves some precious CPU cycles.
