Re: [RFT] Realtek 8168 ethernet support

The patch below agaisnt 2.6.17-rc6 includes the following changes:

commit 3072cc0aba3ac0c944e196a63c4154ca5746ec0b

    r8169: sync with vendor's driver
    
    - add several PCI ID for the PCI-E adapters ;
    - new identification strings ;
    - the RTL_GIGA_MAC_VER_ defines have been renamed to closely match the
      out-of-tree driver. It makes the comparison less hairy ;
    - various magic ;
    - the PCI region for the device with PCI ID 0x8136 is guessed.
      Explanation: the in-kernel Linux driver is written to allow MM register
      accesses and avoid the IO tax. The relevant BAR register was found at
      base address 1 for the plain-old PCI 8169. User reported lspci show that
      it is found at base address 2 for the new Gigabit PCI-E 816{8/9}.
      Typically:
      01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.: Unknown device 8168 (rev 01)
              Subsystem: Unknown device 1631:e015
              Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
              Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
              Latency: 0, cache line size 20
              Interrupt: pin A routed to IRQ 16
              Region 0: I/O ports at b800 [size=256]
              Region 2: Memory at ff7ff000 (64-bit, non-prefetchable) [size=4K]
              ^^^^^^^^
      So far I have not received any lspci report for the 0x8136 and
      Realtek's driver do not help: be it under BSD or Linux, their r1000 driver
      include a USE_IO_SPACE #define but the bar address is always hardcoded
      to 1 in the MM case. :o/

commit 33857396c4f7d171f4ccaca86356df5fe2fdd304

    r8169: remove rtl8169_init_board
    
    Rationale:
    - its signature is not exactly pretty;
    - it has no knowledge of pci_device_id;
    - kiss 23 lines good bye.

commit af50f4372644c3c18c2af697a933c90f2a96be77

    r8169: hardware flow control
    
    The datasheet suggests that the device handles the hardware flow
    control almost automagically. User report a different story, so
    let's try to twiddle the mii registers.

commit 17fb3bf33149eb2cb1a37ff94ab236ab01f91a40

    r8169: mac address change support
    
    Fix for http://bugzilla.kernel.org/show_bug.cgi?id=6032.
    
    Cc: Tim Mattox [off-list ref]
    Signed-off-by: Francois Romieu [off-list ref]

The patch is for review only: mac address change apart, I need to
test it and it will surely conflict with jeff#netdev because of a
recently added PCI ID.
