[PATCH net-next v2 0/4] net: rnpgbe: Add TX/RX and link status support

[Dong Yibo]

Hi maintainers,

This patch series adds the packet transmission, reception, and link status
management features to the RNPGBE driver, building upon the previously
introduced mailbox communication and basic driver infrastructure.

The series introduces:
- Msix/msi interrupt handling with NAPI support
- TX path with scatter-gather DMA and completion handling
- RX path with page pool buffer management
- Link status monitoring and carrier management

These changes enable the RNPGBE driver to support basic tx/rx network operations.
