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.
