cxgb4 firmware missing from pve-firmware package

[Rphoton]

Hello,

I'm a newbie trying to use the native kernel driver for a Chelsio T520-CR 10GB ethernet card.

I'm getting this message on boot:

# dmesg |grep cxgb
[    1.117913] cxgb4 0000:0e:00.4: Direct firmware load for cxgb4/t5fw.bin failed with error -2
[    1.122854] cxgb4 0000:0e:00.4: unable to load firmware image cxgb4/t5fw.bin, error -2
[    1.125993] cxgb4 0000:0e:00.4: Coming up as MASTER: Initializing adapter
[    1.864182] cxgb4 0000:0e:00.4: Direct firmware load for cxgb4/t5-config.txt failed with error -2
[    2.424019] cxgb4 0000:0e:00.4: Successfully configured using Firmware Configuration File "Firmware Default", version 0x0, computed checksum 0x0
[...]

according to a chelsio developer:

That said, "Direct firmware load failed with error -2" indicates the firmware file was not found in userspace. -2 is ENOENT (file not found)

This file seems to be present in this debian package:

https://packages.debian.org/buster/firmware-misc-nonfree


but not in pve-firmware

Should it be there? Should I add some debian or ubuntu repository to install this package? Or is there a way to manually add those files from the vendor? I tried adding them to /lib/firmware/cxgb4/ and running pve-efiboot-tool refresh but that didn't fix it. I'm not sure.

Ok I copied the vendor firmware *.bin files to new filenames matching exactly the ones requested by update-initramfs and run it again.

no more "Possible missing firmware" error from update-initramfs -u, but still one problematic file:

# dmesg |grep cxgb
[    1.111427] cxgb4 0000:0e:00.4: Coming up as MASTER: Initializing adapter
[    1.844199] cxgb4 0000:0e:00.4: Direct firmware load for cxgb4/t5-config.txt failed with error -2
[    2.400035] cxgb4 0000:0e:00.4: Successfully configured using Firmware Configuration File "Firmware Default", version 0x0, computed checksum 0x0

but t5-config.txt is already there. Why is update-initramfs not picking it up?

Is this something that should be fixed in some package? where should I report it?
