Can I reprogram / change the OUI using Wireshark, provided that it is not write protected / read only?

edit

Thank you!

I'm guessing the questioner was thinking of the MAC address of an Ethernet or Wi-Fi adapter. If so, it might be reprogrammable on some adapters, but Wireshark has no code in it to reprogram it as, per the answer, it is a passive monitoring program.

Thanks but I am not looking for the MAC address but the OUI. Anyway, you guys already answered my question, very much appreciated.

The OUI of what? As far as I know, adapters only have an OUI as part of a MAC address. And what is a "phy UID"?

Guy, I was referring to this article:

About 3/4 down:

If you do need to write a PHY driver, the first thing to do is make sure it can be matched with an appropriate PHY device. This is done during bus initialization by reading the device's UID (stored in registers 2 and 3), then comparing it to each driver's phy_id field by ANDing it with each driver's phy_id_mask field. Also, it needs a name. Here's an example:

static struct phy_driver dm9161_driver = { .phy_id = 0x0181b880, .name = "Davicom DM9161E", .phy_id_mask = 0x0ffffff0, ...
