This patch moves the multiple receive queue configuration into a seperate
function from igb_configure_rx. We can essentially do the configuration for
the multiple receive queues just prior to enabling the RX and this will allow
us to seperate the queue enablement from the receive queue layout
configuration.

This patch adds a flags value to the ring that cleans up some of the last

The allocation failed and checksum error stats are currently kept as a
global stat. If we end up allocating the queues to multiple netdevs then
the global counter doesn't make much sense. For this reason I felt it
necessary to move the alloc_rx_buff_failed stat into the rx_stats
portion of the rx_ring.

Since we are writting to the head/tail pointers frequently we might as well
save ourselves some processing time by converting the head and tail offsets
directly to pointers. This will shave a few cycles off the rx/tx path and
allows us to move one step closer to the rings being a bit more independant of
each other.

Add unconditional call to apm_ops.stop() to reset device to low power state
when unloading driver. Some paths have existed to unload driver *without*
resetting device, therefore some errors have persisted through multiple
load/unload cycles, until the whole platform gets rebooted; this is an
attempt to remedy some of those situations. Sorry, I can't seem to find
a bughost.org bug that specifically has these symptoms, but I had it happen
recently here.
Note that this will *not* fix situations in which the PCI express bus has
crashed (evidenced by register reads showing "0xffffffff"), e.g. bughost.org
1855 and 2096; device is unreachable from driver in those cases.

In the paged rx patch (4854fde2), I introduced a bug that could possibly
touch an already freed page. It is fixed by avoiding the access in this
patch. I've also added some comments so that other people touching the
code won't make the same mistake. In the future, if we cannot avoid
access the page after being handled to the upper layer, we can use
get_page/put_page to handle it. For now, it's just not necessary.
