This change updates the igb driver to make use of the netdev_dbg function

This is meant to be provided as an alternative to the patch provided by

It also removes igb_get_time_str since I found that it is unused code that
is no longer used even in debug.

- 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.
