Analyze and fix the following issue in the Linux kernel code: mwl8k: enforce FIF_BCN_PRBRESP_PROMISC when no STA interfaces are active
Problem Details: When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS filter so that we'll only see packets destined for our BSS. But if no STA interfaces have been configured, we would end up passing the BSSID 00:00:00:00:00:00 into the POST_SCAN command, which actually disables the hardware's BSS fi...
