Hi! I will open discussion about mac address and calibration data for wl1251 wireless chip again... Problem: Mac address & calibration data for wl1251 chip on Nokia N900 are stored on second nand partition (mtd1) in special proprietary format which is used only for Nokia N900 (probably on N8x0 and N9 too). Wireless driver wl1251.ko cannot work without mac address and calibration data. Absence of mac address cause that driver generates random mac address at every kernel boot which has couple of problems (unstable identifier of wireless device due to udev permanent storage rules; unpredictable behaviour for dhcp mac address assignment, mac address filtering, ...). Currently there is no way to set (permanent) mac address for network interface from userspace. And it does not make sense to implement in linux kernel large parser for proprietary format of second nand partition where is mac address stored only for one device -- Nokia N900. Driver wl1251.ko loads calibration data via request_firmware() for file wl1251-nvs.bin. There are some "example" calibration file in linux- firmware repository, but it is not suitable for normal usage as real calibration data are per-device specific. So questions are: 1) How to set mac address from userspace for that wl1251 interface? In userspace I can write parser for that proprietary format of nand partition and extract mac address from it 2) How to send calibration data to wl1251 driver? Those are again stored in proprietary format and I can write userspace parser for it. -- Pali Rohár pali.rohar@xxxxxxxxx
