We don't use the normal hotplug mechanism because it doesn't work. It will
load the module some time after the device appears, but that's not good
enough for us -- we need the driver loaded _immediately_ because otherwise
the NIC driver may just abort and then the phy 'device' goes away.

Adding GRO support on top of the HW LRO (TPA) support –
there is no measurable performance drawback of adding GRO
on top of it, and it allows better performance when LRO (TPA)
is turned off for virtualization or bridging.

In case a reset is performed, rtl8169_rx_interrupt() is called from
process context instead of softirq context. Special care must be taken
to call appropriate network core services (netif_rx() instead of
netif_receive_skb()). VLAN handling also corrected.

- Fixed MSIX interrupt configuration to support non contiguous vpaths in
  functions. Four msi-x vectors are reserved per vpath internal to the chip.
  In all, there are 68 msi-x vectors for the 17 vpaths in the chip. In the
  multi function configurations, non-contiguous vpaths are configured to
  represent a function. For instance vpaths 0 and 8 can be configured to
  represent function zero.

- If pci_enable_msix fails for the requested vectors, try with a lesser number
  vectors by reducing the vpath count.

- Fix starvation of receive ring controller when blasted by short packets. This was because the driver was posting 64 rxds initially while the ring controller
was expecting to read 256 replenished rxds. While the driver was coming up,
the internal rxd memory filled up the 64 buffers provided and the ring
controller was left waiting for the remaining 192 rxds to complete the write
back of completed rxds to the host and generation of an interrupt.

- Fix a receive stall due to driver being out of synch with chip. In a corner
case scenario the adapter's ring controller may return a RxD with transfer code
of 0xC, while the host ownership bit is still set to the adapter. The driver
needs to assume that this case where (host_ownership == 1 or adapter) and
(transfer_code == 0xC) is valid, that is, this RxD has been returned by the
receive ring controller but no frame data is associated with the rxd.

- Restore the transfer code field of each newly replenished RxD to 0x0.

- Code cleanup. Removed usage of magic numbers.
