In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

API is not available at this point in the resume flow because

us to seperate the queue enablement from the receive queue layout
configuration.

This change adds a pointer to the netdev to the ring itself. The idea being
at some point in the future it will be possible to support multiple netdevs
from a single adapter struct.

This patch adds a flags value to the ring that cleans up some of the last
remaining items from the ring in order to help seperate it from the adapter
struct. By implementing these flags it becomes possible for different rings
to support different functions such as rx checksumming.

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.

The SRRCTL register exists per ring. Instead of configuring all of them in

this out into the ring specific configuration.

This patch removes the rx_ps_hdr_len which isn't really needed since we can
now use rx_buffer_len less than 1K to indicate that we are in a packet split
mode. We also don't need it since we always use a half page for the data
buffers when receiving so we always know the size to map/unmap.

Counting packets with a good checksum can cause a significant amount of cache
line bouncing due to the shared counter being written to by all of the queues.
In order to avoid this I am removing the counter since we still have the
checksum failed counter which will tell us if there are any issues.

Add a new igb_q_vector data structure to handle interrupts and NAPI. This
helps to abstract the rings away from the adapter struct. In addition it
allows for a bit of consolidation since a tx and rx ring can share a

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.
