Are you using the Reveltronics programmer to brute-force the password? Outside of buying multiple programmers or trying "obvious" passwords, maybe get a pool of people going and divide the space.

Yes, exactly.

We'd need a lot of people with the Programmer + QSFP board though (about 300€ for the hardware), probably not worth it.

So, beware: Newer Mellanox cards (ConnectX-4 / ConnectX-5 and upwards) seem to have a vendor lock for (certain) 40GBit transceivers implemented.

Sadly, the Intel transceivers are locked, means I can't reprogram them. Usually you can just brute force a password (see my thread https://forums.servethehome.com/index.php?threads/transceiver-password-collection.39458/ for some), but the Intel transceivers only do about 100 passwords per second (usually transceivers do 3000), so it would take ages (more than one year in worst case) to brute force the password.
If anyone has the password for those transceivers, please let me know!

I wonder if it might be easier to modify the firmware to remove the vendor lock. I know that it's easy to reflash them, but I don't know whether or not they have some sort of checksum validation.

I found this site which lists which SFPs are compatible with ConnectX-4 cards. I can confirm that Cisco QSFP-40G-SR-BD work in my CX455 cards and link up at 40G.
