Title:
Chelsio T4 has old MSIX PBA offset bug
Status in QEMU:
Invalid
Status in
The device ID on function 7 is 0x which is typically not valid,
there's no entry for it in the PCI IDs database. Someone from Chelsio
would need to explain why it's even exposed, but there doesn't seem to
be any value in quirking it since it provides no useful function.

I was able to boot a VM with just the functions of the device with the
ethernet controller function ID added as PCI devices. Something I
noticed while adding in those devices though is that all of the others
have a description associated with them in Proxmox, but the one that's
causing the boot to
I don't understand the purpose of function 7 on these cards, the class
code indicates an Ethernet device, but without any BARs, I very much
doubt that the functions provide any useful service. Config space is
invalid for the function as QEMU identifies, the referenced BAR resource

PS, this can never be true:
+ (vdev->device_id & 0xff00) == 0x1425))
The lower byte would always be 00. It's the wrong fix anyway, BAR4 is
still missing.
