From: Kalesh AP <[email protected]> While forcing speed to 200G, driver sets the structure variable "bp->link_info->link_signal_mode" value to BNXT_SIG_MODE_PAM4. After that when the user forces the speed back to 25G, this cached value is not set back to BNXT_SIG_MODE_NRZ which results in issuing the HWRM_PORT_PHY_CFG command with wrong inputs.
