-/*
- * Timeline before release:
- * Stage 1: Basic Performance / Capbility fine tune.
- * - Implement PCC -- Dynamic adjustment.
- * - Use NAPI instead of rx_tasklet?
- * PCC Support Both Packet Counter and Timeout Interrupt for
- * receive and transmit complete, does NAPI really needed?
- * I'll add NAPI support anyway..
- * For CPU busy and heavy network loading system..
- * - Try setting 64bit DMA with pci_set[_consistent]_dma_mask
- * and set netdev feature flag.
- * (Need to modity transmit descriptor filling policy as well)
- * - Use pci_map_page instead of pci_map_single for HIGHMEM support
- *
- * Stage 2: Error handling.
- * - Wathch dog
- * - Transmit timeout
- *
- * Stage 3: Basic offloading support.
- * - Implement scatter-gather offloading.
- * A system page per RX (buffer|descriptor)?
- * Handle fraged sk_buff to TX descriptors.
- * - Implement tx/rx ipv6/ip/tcp/udp checksum offloading
- *
- * Stage 4: Basic feature support.
- * - Implement Power Managemt related functions.
- * - Implement Jumboframe.
- * - Implement MSI.
- *
- * Stage 5: Advanced offloading support.
- * - Implement VLAN offloading.
- * - Implement TCP Segement offloading.
- *
- * Stage 6: CPU Load balancing.
- * - Implement MSI-X.
- * Along with multiple RX queue, for CPU load balancing.
- * - Use Multiple TX Queue for Multiple CPU Transmit
- * Simultaneously Without Lock.
- *
- * Stage 7:
- * - Cleanup/re-orginize code, performence tuneing(alignment etc...).
- * - Test and Release 1.0
