> miniCQE formats for Flow Tag and L3/L4 Header compression are only
> supported by Mellanox FW starting version 16.29.392. There is no point to
> allow user to enable these formats if FW cannot provide them.
> Check FW capabilities and deny user requests if the selected miniCQE format
> is not supported by an underlying NIC.
