Subject: [PATCH 0/3] net/ncsi: Add NC-SI 1.2 Get MC MAC Address command

NC-SI 1.2 isn't officially released yet, but the DMTF takes way too long
to finalize stuff, and there's hardware out there that actually supports
this command (Just the Broadcom 200G NIC afaik).

The work in progress spec document is here:

The command code is 0x58, the command has no data, and the response
returns a variable-length array of MAC addresses for the BMC.

I've tested this out using QEMU emulation (I added the Mellanox OEM Get
MAC Address command to libslirp a while ago [1], although the QEMU code
to use it is still not in upstream QEMU [2] [3]. I worked on some more
emulation code for this as well), and on the new Broadcom 200G NIC.

The Nvidia ConnectX-7 NIC doesn't support NC-SI 1.2 yet afaik. Neither
do older versions in newer firmware, they all just report NC-SI 1.1.

Let me know what I can do to change this patch to be more suitable for
upstreaming, I'm happy to work on it more!
