Paul Gortmaker 70c7160619 Add appropriate <linux/prefetch.h> include for prefetch users
After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.

 =========================================
 #!/bin/bash
 MANUAL=""
 for i in `git grep -l 'prefetch(.*)' .` ; do
 	grep -q '<linux/prefetch.h>' $i
 	if [ $? = 0 ] ; then
 		continue
 	fi

 	(	echo '?^#include <linux/?a'
 		echo '#include <linux/prefetch.h>'
 		echo .
 		echo w
 		echo q
 	) | ed -s $i > /dev/null 2>&1
 	if [ $? != 0 ]; then
 		echo $i needs manual fixup
 		MANUAL="$i $MANUAL"
 	fi
 done
 echo ------------------- 8\<----------------------
 echo vi $MANUAL
 =========================================

David Decotigny 7073949720 ethtool: cosmetic: Use ethtool ethtool_cmd_speed API
This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.

For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.

All drivers compiled with make allyesconfig ion x86_64 have been
updated.

Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

Roopa Prabhu b3abfbd295 enic: Add support for PORT_REQUEST_PREASSOCIATE_RR
Current enic code only supports ASSOCIATE and DISASSOCIATE port profile
operations. This patch adds enic support for port profile
PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable
of handling port profile requests done in two steps namely PREASSOCIATE_RR
and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly
from its use as an optimization during VM migration ie, to do resource
reservation on destination host before resources on source host are released.

PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE,
8021qbh will also need to support VDP commands.

In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation
this patch also does the below:
- Introduces handlers for PORT_REQUEST operations
- Moves most of the port profile handling code to new files enic_pp.[ch]
- Uses new fw devcmds for port profile operations

Roopa Prabhu 9085fd0985 enic: Add support for new fw devcmds for port profile handling
This patch introduces new fw devcmds for port profile handling.
These new commands are similar to the current fw commands for
port profile handling. The only difference being that the new
commands split the existing port profile handling devcmds into multiple
fw commands, giving the driver finer control over port profile operations.

Vasanthy Kolluri 1cbb1a61d5 enic: Always use single transmit and single receive hardware queues per device
We believe that our earlier patch for supporting multiple hardware
receive queues per enic device requires more internal testing. At this
point, we think that it's best to disable the use of multiple receive
queues. The current patch provides an effective means for the same.

Also, we continue to disallow multiple hardware transmit queues per
device. But change the way we enforce this in order to maintain
consistency with the way receive queues are handled.

Roopa Prabhu 4dce2396b3 enic: Bug Fix: Dont reset ENIC_SET_APPLIED flag on port profile disassociate
enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED
flag is set. A recent rework of enic_set_port_profile added code to reset this
flag on disassociate. As a result of which a client calling enic_get_vf_port
to get the status of port profile disassociate will always get a return value
of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate
ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the
flag is set both at associate and disassociate of a port profile.

Tejun Heo 23f333a2bf drivers/net: don't use flush_scheduled_work()
flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.

Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb.  There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances.  However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

Roopa Prabhu 90cf0b53d7 enic: Add support for firmware management device
This patch adds support for firmware management device in enic driver.
A management device is a virtual PCIe device that firmware can present
to the host as its management endpoint. It provides the interface between
the host and adapter firmware for all management operations.

Ben Hutchings 1437ce3983 ethtool: Change ethtool_op_set_flags to validate flags
ethtool_op_set_flags() does not check for unsupported flags, and has
no way of doing so.  This means it is not suitable for use as a
default implementation of ethtool_ops::set_flags.

Add a 'supported' parameter specifying the flags that the driver and
hardware support, validate the requested flags against this, and
change all current callers to pass this parameter.

Change some other trivial implementations of ethtool_ops::set_flags to
call ethtool_op_set_flags().
