From: Rakesh Kudurumalla <[email protected]> Add ROC APIs for Forward Error Correction (FEC) configuration: - roc_nix_mac_fec_set: Set FEC mode on the link - roc_nix_mac_fec_supported_get: Query supported FEC modes from firmware
These APIs use CGX mailbox messages to configure and query FEC parameters on PF interfaces.
