Note that ports of T5 cards are named cxl and attach to a t5nex parent device

(in contrast to ports named cxgbe that attach to a t4nex parent for a T4 card).
|
||||
Loader tunables with the hw.cxgbe prefix apply to both T4 and T5 cards.
|

The sysctl MIBs are at dev.t5nex and dev.cxl for T5 cards and at dev.t4nex and
|

dev.cxgbe for T4 cards.

For example, a T5 adapter will provide port MIBs under dev.cxl and

adapter-wide MIBs under dev.t5nex.
