Hi!

I’m right now working on the low-level configuration of a Mellanox ConnectX-5 (MT27800 family) with mstmcra-command. Thus I’m wondering whether there is some official documentation of the low-level device registers of these Cards and their functionality.

Thanks in advance!

I’m still trying to understand how ICRC can be disabled on a Mellanox ConnectX-5 card (MT27800 family). I’ve found scripts online that pretend to do exactly this for various Mellanox-cards by manipulating a set of device registers with the mstmcra-command, but a source for their choice of registers is nowhere to be found. I would like to verify my mstmcra-commands with the official documentation of the device registers of the Mellanox-cards.
