> The function mlx5_set_min_inline() includes a switch() that checks
> various PCI device IDs in order to set the txq_inline_min value.  No
> value is set when the PCI device ID matches the ConnectX-5 adapters,
> resulting in an assert() failure later in the function
> mlx5_set_txlimit_params().
> 
> This error was encountered on an IBM Power 9 system running RHEL 7.6
> w/o Mellanox OFED installed.
