V2-changes: - compilation fixes. V1-changes: This series adds new PMD features to the ENETC4 driver targeting the NXP i.MX95 NETC IP.
The series covers: - KEEP_CRC Rx offload: preserve the Ethernet FCS in the receive buffer. - TSO: TCP Segmentation Offload for the VF Tx path. - RSC/LRO: hardware Receive Segment Coalesce for PF and VF Rx paths. - Link speed code: extend the PF-to-VF mailbox field from 4-bit to 8-bit to support speeds beyond 10G. - Firmware version: report the NETC IP version via fw_version_get. - Register dump: dump SI, port (PF) and BD ring registers. - Ring parameters: implement rxq_info_get / txq_info_get for the VF. - Link-up interrupt: refresh the cached link speed on each VF link-up interrupt so that link_update returns the current speed immediately. - Stats reset: software snapshot/delta approach for VF counter reset. - Per-queue Rx interrupt: MSI-X per-queue Rx interrupts for the VF, enabling interrupt-driven receive with l3fwd-power. - SI VLAN: hardware port VLAN insertion/removal for PF and VF. - VF link status bitmask: switch VF link status to bitmask encoding to align with the PF and newer kernel driver conventions. - TX PAUSE: VF sets Rx congestion mode when the PF signals TX PAUSE negotiated on the wire; adds Flow control = Y to enetc4.ini. - WRR Tx scheduler: per-ring WRR weights via enetc4_txq_wrr devarg.
