Vasanthy Kolluri ea0f0d8bc6 enic: Support newer version of firmware devcmd CMD_MCPU_FW_INFO
This patch provides support to the newer version of firmware devcmd CMD_MCPU_FW_INFO
that returns additional information (ASIC type and revision) about the underlying hardware.
This knowledge is required by the driver to implement any hardware specific features.

Roopa Prabhu 8da83f8e73 enic: Flush driver cache of registered addr lists during port profile disassociate
During a port profile disassociate all address registrations for the interface
are blown away from the adapter. This patch resets the driver cache of
registered address lists to zero after a port profile disassociate.

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.

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.

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.

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().

Vasanthy Kolluri 99ef563901 enic: Use a lighter reset operation for enic devices
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.

Vasanthy Kolluri f8cac14acf enic: Bug Fix: Change hardware ingress vlan rewrite mode
The current ingress vlan rewrite mode setting lets the hardware strip off
the tag control information of a packet received on native vlan. As a
result, the priority bits are also lost. The fix is to change the ingress
vlan rewrite mode setting such that the complete tag control information is
retained for packets that belong to native vlan.

Randy Dunlap d49aba84fe enic: fix pci_alloc_consistent argument
Fix build warning on i386 (32-bit) with 32-bit dma_addr_t:

drivers/net/enic/vnic_dev.c: In function 'vnic_dev_init_prov':
drivers/net/enic/vnic_dev.c:716: warning: passing argument 3 of 'pci_alloc_consistent' from incompatible pointer type
include/asm-generic/pci-dma-compat.h:16: note: expected 'dma_addr_t *' but argument is of type 'u64 *'

Now builds without warnings on i386 and on x86_64.
