From 8921d04e8df7475d733d853564bdb001e83bf33f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 27 Dec 2012 18:26:42 +0100 Subject: mac80211: track number of spatial streams With VHT, a station can change the number of spatial streams it can receive on the fly, not unlike spatial multiplexing in HT. Prepare for that by tracking the maximum number of spatial streams it can receive when the connection is established.
