From e552af058148498c8a0874edf6b022caea9cb2b7 Mon Sep 17 00:00:00 2001 From: Haim Dreyfuss Date: Wed, 28 Mar 2018 13:24:10 +0300 Subject: mac80211: limit wmm params to comply with ETSI requirements ETSI has recently added new requirements that restrict the WMM parameter values for 5GHz frequencies. We need to take care of the following scenarios in order to comply with these new requirements: 1. When using mac80211 default values; 2. When the userspace tries to configure its own values; 3. When associating to an AP which advertises WWM IE. When associating to an AP, the client uses the values in the advertised WMM IE. But the AP may not comply with the new ETSI requirements, so the client needs to check the current regulatory rules and use those limits accordingly.
