E.g.: if I see "phy#0" string as physical interface name in "iw reg get" output, then iw must accept "phy#0" string as correct physical interface name in "iw phy <phyname> reg get" input: ``` $ iw phy phy0 reg get | grep phy phy#0 $ iw phy phy#0 reg get command failed: No such file or directory (-2) ``` I prefer to use phy names without "#" prefix for phy number - in unique form with 'iw list | grep Wiphy' command. ### 2) Fix "iw reg" command to show all devices "iw reg" command must show all devices, listed in "iw list". ### 3) Fix "iw reg" command to set regulatory domain really for all devices Global variant of "iw reg set <COUNTRY>" command must set regulatory domain really for all devices. ### 4) Add command to set regulatory domain per phy by phy name Example: ``` iw phy0 reg set BR ``` ### 4) Add command to set regulatory domain per phy by device name Example: ``` iw dev wlan0 reg set BR ``` Inside iw, device name "wlan0" transformed to his phy name "phy0", and regulatory domain configured to those "phy0" physical interface.
