Add interfaces for drivers to call for recording number of packets and
bytes at send time and transmit completion. Also, added a function to
"reset" a queue. These will be used by Byte Queue Limits.

Change the kconfig types to tristate and adjust the condition for
declaring net_device::dsa_ptr to allow for this.
Adjust the makefile so that if NET_DSA_MV88E6123_61_65=y and
NET_DSA_MV88E6131=m or vice versa then both drivers are built-in. We
could leave these options as bool and make NET_DSA_MV88E6XXX a
user-selected option, but that would break existing configurations.

This patch adds in the infrastructure code to create the network priority
cgroup. The cgroup, in addition to the standard processes file creates two
control files:
1) prioidx - This is a read-only file that exports the index of this cgroup.
This is a value that is both arbitrary and unique to a cgroup in this subsystem,
and is used to index the per-device priority map
2) priomap - This is a writeable file. On read it reports a table of 2-tuples
<name:priority> where name is the name of a network interface and priority is
indicates the priority assigned to frames egresessing on the named interface and
originating from a pid in this cgroup
This cgroup allows for skb priority to be set prior to a root qdisc getting
selected. This is benenficial for DCB enabled systems, in that it allows for any
application to use dcb configured priorities so without application modification

net: Remove LL_ALLOCATED_SPACE
The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the
alignment to the sum of needed_headroom and needed_tailroom. As
the amount that is then reserved for head room is needed_headroom
with alignment, this means that the tail room left may be too small.
Now that all uses of LL_ALLOCATED_SPACE have been removed, this
patch finally removes the macro itself.

Most machines dont use RPS/RFS, and pay a fair amount of instructions in
netif_receive_skb() / netif_rx() / get_rps_cpu() just to discover
RPS/RFS is not setup.
Add a jump_label named rps_needed.
If no device rps_map or global rps_sock_flow_table is setup,
netif_receive_skb() / netif_rx() do a single instruction instead of many
ones, including conditional jumps.

This adds the /sys/class/net/DEV/queues/Q/tx_timeout attribute

Remove it from the new location instead.

Fairly nasty conflicts with the sysfs rb-tree usage, conflicting
with Eric Biederman's changes for tagged directories.
Add configuration setting for drivers to turn spoof checking on or off
for discrete VFs.
v2 - Fix indentation problem, wrap the ifla_vf_info structure in
#ifdef __KERNEL__ to prevent user space from accessing and
change function paramater for the spoof check setting netdev
op from u8 to bool.
v3 - Preset spoof check setting to -1 so that user space tools such
as ip can detect that the driver didn't report a spoofcheck
setting. Prevents incorrect display of spoof check settings
for drivers that don't report it.

This patch does several things:
- introduces __ethtool_get_settings which is called from ethtool code and
from drivers as well. Put ASSERT_RTNL there.
- dev_ethtool_get_settings() is replaced by __ethtool_get_settings()
- changes calling in drivers so rtnl locking is respected. In
iboe_get_rate was previously ->get_settings() called unlocked. This
fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same
problem. Also fixed by calling __dev_get_by_index() instead of
dev_get_by_index() and holding rtnl_lock for both calls.
- introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create()
so bnx2fc_if_create() and fcoe_if_create() are called locked as they
are from other places.
- use __ethtool_get_settings() in bonding code

bnx2fc driver calls netdev->netdev_ops->ndo_fcoe_get_wwn() and it may not
be defined with the current Kconfig dependencies. ndo_fcoe_get_wwn is
dependent on CONFIG_FCOE, but bnx2fc does not select CONFIG_FCOE, as it does
not depend on fcoe driver. Since both fcoe and bnx2fc drivers select
CONFIG_LIBFCOE, define NETDEV_FCOE_WWNN and NETDEV_FCOE_WWPN when
CONFIG_LIBFCOE is defined.
