My question is regarding the wl1251 driver implementation for TI chipsets: * Does the chipset/current implementation support sleep/awake triggers? (or at least quiet elements?) -> This means, can I command the NIC to stay quiet (slept) for certain duration of time? My plan is to implement/test a Notice of Absence protocol where the driver would trigger absent (quiet/sleep) periods according to the beacon's NoA IE. Ive seen in the code the wl1251_ps_elp_sleep/wakeup functions that might be reused for this purpose (?) * Last (lazy) question. AFAIK only the google dev 1 phone uses this chipset. Is there any 1ghz android device that could benefit of this driver? Thanks for your answer, Andr?s
