If anyone has any objections, please let me know. ------------------ From: Ilan Peer [ Upstream commit 6508de0305d560235b366cc2cc98f7bcfb029e92 ] In the scheduler config command, the meaning of tid == 0xf was intended to indicate the configuration is for management frames. However, tid == 0xf was also used for the multicast queue that was meant only for multicast data frames, which resulted with the FW not encrypting multicast data frames. As multicast frames do not have a QoS header, fix this by setting tid == 0, to indicate that this is a data queue and not management one.
