Can't find the firmware of MT26428: MT_0D20110009

Hi all, I currently manage an old server with an InfiniBand card. I want to look for the latest firmware for it, but I can’t find this board_id, I want to know which product it is. Do a google search and it used to appear in some Mellanox OFED Linux User’s Manual. I want to find a compatible one, and then force flash it.
