New X4522 (dual port SFP56) and X4542 (dual port QSFP56) adaptors are Medford4 (X4) chips that are based on EF10 architecture. An X4 NIC supports multiple network engine types. This series provides support only for the Medford2-alike, 'full-feature' (FF) network engine. This shall not be confused with the concept of 'datapath FW variants': the FF network engine supports both 'full-feature' and 'ultra-low-latency' datapath FW variants, with corresponding Medford2-alike feature sets.
The first part of the series provides general support for the adaptors, whilst the second one adds support for the new management controller interface for configuration of network port features (netport MCDI). For now, only support for physical functions (PFs) is concerned. There is a small number of TODO and FIXME markings in the code. Those are normal at this development stage and will be removed by future patches when VF support has fleshed out. v2: - squashed respective parts of commit [1] into commits [2] and [3] - dropped irrelevant TODO and FIXME markings from the patches - applied review notes and tested build in FreeBSD14-64 [1] https://mails.dpdk.org/archives/dev/2025-April/317109.html [2]
