From df1404650ccbfeb76a84f301f22316be0d00a864 Mon Sep 17 00:00:00 2001

Subject: [PATCH] mac80211: remove support for IFF_PROMISC

This support is essentially useless as typically networks are encrypted,
frames will be filtered by hardware, and rate scaling will be done with
the intended recipient in mind. For real monitoring of the network, the
monitor mode support should be used instead.

Removing it removes a lot of corner cases.
