I might be missing something here ... as far as I understood the P2P Device management interface should not be visible to the higher layers, and it should not be accessed directly. In case that a dedicated P2P Device interface is used there is no way to flush the BSS table other than accessing it directly (this is required in some of the hwsim tests).

Some of the P2P Device flows rely on the data that is in the BSS table, and as such I thought that clearing it as part of the P2P flush flow made sense. Regardless, at least for the hwsim tests, we need a way to flush the BSS table when a P2P Device interface is used.
Thanks in advance,
