Michał Mirosław 0d0b16727f net: Fix drivers advertising HW_CSUM feature to use csum_start
Some drivers are using skb_transport_offset(skb) instead of skb->csum_start
for NETIF_F_HW_CSUM offload.  This does not matter now, but if someone
implements checksumming of encapsulated packets then this will break silently.

TSO output paths are left as they are, since they are for IP+TCP only
(might be worth converting though).

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.

Roopa Prabhu 29639059a0 enic: Use VF mac set by IFLA_VF_MAC in port profile provisioning data
This patch adds support in enic 802.1Qbh port profile provisioning code
to use the mac address set by IFLA_VF_MAC. For now we handle this mac as a
special case for a VM mac address sent to us by libvirt. The VM mac address
is sent to the switch along with the rest of the port profile provisioning
data. This patch also adds calls to register and deregister the mac address
during port profile association/deassociation.

Jesse Gross eab6d18d20 vlan: Don't check for vlan group before vlan_tx_tag_present.
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.

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().

The port profile information for a dynamic enic device is set by the upper
layers, that are oblivious to the device reset operation. We do not want a
reset operation erase the network state of a dynamic enic device as there
is no way to set up the port profile information again. Hence a lighter
reset operation called hang reset is used. Hang reset, unlike soft reset
does not reset the network state and resets the host side state only.

Scott Feldman f8bd909183 net: Add ndo_{set|get}_vf_port support for enic dynamic vnics
Add enic ndo_{set|get}_vf_port ops to support setting/getting
port-profile for enic dynamic devices.  Enic dynamic devices are just like
normal enic eth devices except dynamic enics require an extra configuration
step to assign a port-profile identifier to the interface before the
interface is useable.  Once a port-profile is assigned, link comes up on the
interface and is ready for I/O.  The port-profile is used to configure the
network port assigned to the interface.  The network port configuration
includes VLAN membership, QoS policies, and port security settings typical
of a data center network.

A dynamic enic initially has a zero-mac address.  Before a port-profile is
assigned, a valid non-zero unicast mac address should be assign to the
dynamic enic interface.
