Nice, will that support BPI-R4 (with wifi7 module mt7996e ) MLO also?
And you will do smth like this?
phy#0
Interface wlan0
ifindex 51
wdev 0x23
addr 02:03:7f:12:34:56
ssid MLO-AP
type AP
link 0:
addr 02:03:7f:12:34:56
channel 11 (2462 MHz), width: 20 MHz, center1: 2462 MHz
txpower 20.00 dBm
link 1:
addr 02:03:7f:12:35:57
channel 36 (5180 MHz), width: 80 MHz, center1: 5210 MHz
txpower 22.00 dBm
link 2:
addr 00:03:7f:12:36:59
channel 37 (6135 MHz), width: 320 MHz, center1: 6105 MHz
txpower 21.00 dBm
Could I clone some MLO test code for BPI-R4?
