It is expected to advertise only the speeds that the device is
capable to offer.

Good example:
drivers/net/i40e/i40e_ethdev.c
if (I40E_PHY_TYPE_SUPPORT_40G(hw->phy.phy_types))
/* For XL710 */
dev_info->speed_capa = ETH_LINK_SPEED_40G;
else if (I40E_PHY_TYPE_SUPPORT_25G(hw->phy.phy_types))
/* For XXV710 */
dev_info->speed_capa = ETH_LINK_SPEED_25G;
else
/* For X710 */
dev_info->speed_capa = ETH_LINK_SPEED_1G | ETH_LINK_SPEED_10G;
Bad example:
drivers/net/bnx2x/bnx2x_ethdev.c
dev_info->speed_capa = ETH_LINK_SPEED_10G | ETH_LINK_SPEED_20G;
Looking at qlogic.com, only some 57840 adapters are capable of 20G.
