The __dev* removal patches for the network drivers ended up messing up
the function prototypes for a bunch of drivers. This patch fixes all of
them back up to be properly aligned.
Bonus is that this almost removes 100 lines of code, always a nice

This change is meant to both improve the performance and reduce the size of
igb_tx_map. To do this I have expanded the work done in the main loop by
pushing first into tx_buffer. This allows us to pull in the dma_mapping_error
check, the tx_buffer value assignment, and the initial DMA value assignment to
the Tx descriptor. The net result is that the function reduces in size by a
little over a 100 bytes and is about 1% or 2% faster.

This change is meant to improve the efficiency of the Tx flags in igb by
aligning them with the values that will later be written into either the
cmd_type or olinfo. By doing this we are able to reduce most of these
functions to either just a simple shift followed by an or in the case of
cmd_type, or an and followed by an or in the case of olinfo.
In order to avoid type conversion errors I also adjusted the locations
where we were switching between CPU and little endian.

Where a PTP clock driver is associated with a net or PHY driver, it
should be enabled automatically whenever that driver is enabled.
Therefore:
- Make PTP clock drivers select rather than depending on PTP_1588_CLOCK
- Remove separate boolean options for PTP clock drivers that are built
as part of net driver modules. (This also fixes cases where the PTP
subsystem is wrongly forced to be built-in.)
- Set 'default y' for PTP clock drivers that depend on specific net
drivers but are built separately

This change helps to address locking issues seen with
netif_set_real_num_tx_queues and netif_set_real_num_rx_queues when used in
the igb_set_interrupt_capability function. To resolve these locking issues
I have moved the two function calls into __igb_open so that they can be
called while the RTNL lock is held.
An added advantage to this is that the number of queues is not updated
until the last possible moment so if there are any issues in allocating
MSI-X interrupts or resources for the rings we have time to change the
values prior to updating the netdev.

Pull networking changes from David Miller:
1) GRE now works over ipv6, from Dmitry Kozlov.
2) Make SCTP more network namespace aware, from Eric Biederman.
3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.
4) Make openvswitch network namespace aware, from Pravin B Shelar.
5) IPV6 NAT implementation, from Patrick McHardy.
6) Server side support for TCP Fast Open, from Jerry Chu and others.
7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
Borkmann.
8) Increate the loopback default MTU to 64K, from Eric Dumazet.
9) Use a per-task rather than per-socket page fragment allocator for
outgoing networking traffic. This benefits processes that have very
many mostly idle sockets, which is quite common.
From Eric Dumazet.
10) Use up to 32K for page fragment allocations, with fallbacks to
smaller sizes when higher order page allocations fail. Benefits are
a) less segments for driver to process b) less calls to page
allocator c) less waste of space.
From Eric Dumazet.
11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.
12) VXLAN device driver, one way to handle VLAN issues such as the
limitation of 4096 VLAN IDs yet still have some level of isolation.
From Stephen Hemminger.
13) As usual there is a large boatload of driver changes, with the scale
perhaps tilted towards the wireless side this time around.
Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

This change is meant to improve performance on systems that do not require
the DMA unmap calls. On those systems we do not need to make use of the
unmap address for Tx or the unmap length so we can drop both thereby
reducing the size of the Tx buffer info structure.
In addition I have changed the logic to check for unmap length instead of
unmap address when checking to see if a buffer needs to be unmapped from
DMA use. The reasons for this change is that on some platforms it is
possible to receive a valid DMA address of 0 from an IOMMU.

Instead of storing the RSS key as a character array we can simplify the

This change will produce the same exact key, the only difference is that I
translated the u8 array to a u32 array which will be correctly ordered on
writes to hardware by the cpu_to_le32 operations that are built into the
