Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.

This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers.  In
addition, by enabling all the new Kconfig options does not add
any un-expected options.

The is does a general cleanup of the drivers/net/ Kconfig and
Makefile.  This patch create a "core" option and places all
the networking core drivers into this option (default is yes
for this option).  In addition, it alphabitizes the Kconfig
driver options.

As a side cleanup, found that the arcnet, token ring, and PHY
Kconfig options were a tri-state option and should have been
a bool option.

After moving the skfp driver, issues with the #include pathing to
their locel headers was somehow exposed.  Several headers had the
incorrect path, so they were not able to be found during compile
time.

This patch fixes up the path issues to the local headers that need
to be included.

This patch helps to simplify the work being done by the transmit path by
removing the unnecessary compares between count and the work limit.  Instead
we can simplify this by just adding a budget value that will act as a count

Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM.
Removing this needs deeper surgery.

Since ixgbevf doesn't change hardware state on RX csum enable/disable
its reset is avoided.

Things noticed:
 - HW VLAN acceleration probably can be toggled, but it's left as is
 - the resets on RX csum offload change can probably be avoided
 - there is A LOT of copy-and-pasted code here

Compute statistics per ring using 64 bits, and provide
network device stats in 64 bits.

It should make this driver multiqueue operations faster (no more cache
line ping pongs on netdev->stats structure)

Use u64_stats_sync infrastructure so that its safe on 32bit arches as
well.

Virtual Machines with emulated e1000 network adapter running on Parallels'
server were seeing kernel panics due to the e1000 driver dereferencing an
unexpected NULL pointer retrieved from buffer_info->skb.

The problem has been addressed for the e1000e driver, but not for the e1000.
Since the two drivers share similar code in the affected area, a port of the
following e1000e driver commit solves the issue for the e1000 driver:

commit 9ed318d5
Author: Tom Herbert <therbert@google.com>
Date:   Wed May 5 14:02:27 2010 +0000

    e1000e: save skb counts in TX to avoid cache misses

    In e1000_tx_map, precompute number of segements and bytecounts which
    are derived from fields in skb; these are stored in buffer_info.  When
    cleaning tx in e1000_clean_tx_irq use the values in the associated
    buffer_info for statistics counting, this eliminates cache misses
    on skb fields.
