[PATCH v2 00/14] net/enetc: add new features for ENETC4 VF on i.MX9

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.
