For anyone with chelsio network cards. if you are planning to downgrade to 11.2 from 11.3 or even 12.0 you will also need to downgrade the firmware on the card.
hw.cxgbe.fw_install
0 prohibits the driver from installing a firmware on the card. 1
allows the driver to install a new firmware if internal driver
heuristics indicate that the new firmware is preferable to the
one already on the card. 2 instructs the driver to always in-
stall the new firmware on the card as long as it is compatible
with the driver and is a different version than the one already
on the card. The default is 1.
In tunables set hw.cxgbe.fw_install as the variable
value set to 2 and reboot.
chnage this back to 1 once you see your card and reboot again. then you can delete the tune.
Hopefully this helps someone else!
