I think the following code is simpler and shows intent clearer?
No objection to the patch above from me, just a suggestion :)


device_info->speed_capa = ETH_LINK_SPEED_10G | ETH_LINK_SPEED_40G;

if (CHELSIO_CHIP_VERSION(adapter->params.chip) == CHELSIO_T6)
	device_info->speed_capa |= ETH_LINK_SPEED_100G;
