Hi, We noticed that our transmit throughput dropped by ~20-30% and bisected the issue to this patch. We will dig around a bit more to investigate why this seems to be happening... - Rory On 5/27/24 09:06, Miri Korenblit wrote: > From: Johannes Berg <johannes.berg@intel.com> > > 6 GHz BSS SP client shall respect TX power limits advertised > by the AP in TPE elements, send the data to the firmware using > the AP_TX_POWER_CONSTRAINTS_CMD command, so do that. > > Co-developed-by: Mukesh Sisodiya <mukesh.sisodiya@intel.com> > Signed-off-by: Mukesh Sisodiya <mukesh.sisodiya@intel.com> > Signed-off-by: Johannes Berg <johannes.berg@intel.com> > Signed-off-by: Miri Korenblit <miriam.rachel.korenblit@intel.com> > --- > .../net/wireless/intel/iwlwifi/mvm/mac80211.c | 11 ++++ > .../wireless/intel/iwlwifi/mvm/mld-mac80211.c | 55 ++++++++++++++++--- > drivers/net/wireless/intel/iwlwifi/mvm/mvm.h | 6 ++ > 3 files changed, 63 insertions(+), 9 deletions(-) > > diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c b/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c > index 752fdb6a783f..88bc0baabf7e 100644 > --- a/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c > +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c > @@ -2768,6 +2768,13 @@ iwl_mvm_bss_info_changed_station_common(struct iwl_mvm *mvm, > > if (changes & BSS_CHANGED_BANDWIDTH) > iwl_mvm_update_link_smps(vif, link_conf);

I noticed the patch you send to which Johannes replied to stating a similar fix is already in -rc1. But you reported this a few days after -rc1 was out, which makes me wonder if this really is resolved. If it is: apologies for the noise in advance.

We independently pulled in this patch series without the earlier fix, which caused an issue only in our forked kernel, and the confusion on our end. My mistake for reporting the issue here. - Rory
