Probably not a such. I don't think we have any drivers for bridge
devices so I don't think it matters. It likely wouldn't hurt to fix
it just in case though.
Do any of the mellanox cards do anything with the bridge on the card?
If you fix the offsets and diff this against my last fix (to never
free the buffer) I think your patch makes sense.
This appears to be the proper test.
These look like the proper two registers to save.
Unless I am completely misreading the spec. While you have picked the
right register to save the offsets should be 0x08 and 0x0c or 8 and 12....
