Subject: wifi: iwlwifi: mvm: remove old PASN station when adding a new one
From: Avraham Stern <avraham.stern@intel.com>
[ Upstream commit dbfff5bf9292714f02ace002fea8ce6599ea1145 ]
If a PASN station is added, and an old PASN station already exists
for the same mac address, remove the old station before adding the
new one. Keeping the old station caueses old security context to
be used in measurements.
