No, the driver doesn't support this.

Here's a write up that I found.

The MAC address can be modified by editing the nvs_map.bin file.  Any
binary editor can be used for this purpose (e.g. HxD - Freeware Hex
Editor and Disk Editor).



The MAC address field in the nvs_map.bin is defined as follows:

nvs_map.bin address offset       MAC address

0x3 - 0x6                        Local station MAC address LSB

0xA - 0xD                        Local station MAC address MSB



For more details, see:

For testing  I changed our wireless MAC address from 08-00-28-32-e4-59
to 08-00-28-01-02-03.

first 16 bytes (MAC: 08-00-28-32-e4-59):

01 6D 54 59 E4 32 28 01 71 54 00 08 00 00 00 00

changed to (MAC: 08-00-28-01-02-03):

01 6D 54 03 02 01 28 01 71 54 00 08 00 00 00 00



The nvs_map.bin file needs to be transferred to QNX target (over
network, SD card, USB stick ...) and then linked to specific locations
as follows. I copied the nvs_map_cal-mac-01-02-03.bin to NAND flash on
J5 which was mounted under /var.
