The use case of sending a DELBA to control a block ack agreement sounds exactly like a case that I was worried about when injecting arbitrary frames without informing the local stack about that.. Isn't the appropriate approach for addressing that to provide such capability in the kernel? If this is just to have a temporary workaround for not wanting to update a kernel for some systems, it does not really sound like a convincing argument to complicate upstream hostapd with a feature that would then likely need to be maintained for significant amount of time in practice. -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
