enic: add vxlan offload support
This series adds vxlan offload support for enic driver. The first
patch adds vxlan devcmd for configuring vxland offload parameters.
Second patch adds ndo_udp_tunnel_add/del and offload on rx path.
There are to modes in which fw supports vxlan offload.
mode 0: fcoe bit is set for encapsulated packet. fcoe_fc_crc_ok is set
if checksum of csum is ok. This bit is or of ip_csum_ok and
tcp_udp_csum_ok
mode 2: BIT(0) in rss_hash is set if it is encapsulated packet.
BIT(1) is set if outer_ip_csum_ok/
BIT(2) is set if outer_tcp_csum_ok
Some hw supports only mode 0, some support mode 0 and 2. Driver gets
the supported modes bitmap using get_supported_feature_ver devcmd
and selects the highest mode both driver and fw supports.
Third patch adds offload support on tx path by adding
enic_features_check().
v2: Order local variable declarations from longest to shortest line,
on all three patches.

Now when sending stream reset request, it closes the streams to
block further xmit of data until this request is completed, then
calls sctp_send_reconf to send the chunk.
But if sctp_send_reconf returns err, and it doesn't recover the
streams' states back, which means the request chunk would not be
queued and sent, so the asoc will get stuck, streams are closed
and no packet is even queued.
This patch is to fix it by recovering the streams' states when
it fails to send the request, it is also to fix a return value.

Add support for RX checksum offload of encapsulated packets. This
essentially just means paying attention to the inner checksum flags
in the RX event, and if *either* checksum flag indicates a fail then
don't tell the kernel that checksum offload was successful.
Also, count these checksum errors and export the counts to ethtool -S.
Test the most common "good" case of RX events with a single bitmask
instead of a series of ifs. Move the more specific error checking
in to a separate function for clarity, and don't use unlikely() there
since we know at least one of the bits is bad.

* If no queues are created, don't call xennet_disconnect_backend as

* If setup_netfront() fails, ensure that all the queues created are

Pull SCSI target fixes from Nicholas Bellinger:
"This target series for v4.10 contains fixes which address a few
long-standing bugs that DATERA's QA + automation teams have uncovered
while putting v4.1.y target code into production usage.
We've been running the top three in our nightly automated regression
runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary
Guo has been manually verifying against a four node ESX cluster this
past week.
Note all of them have CC' stable tags.
Summary:
- Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT
status, where target_core_xcopy.c logic was incorrectly returning
SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon
Vincent)
- Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are
being aborted, before the new one had been dispatched into tmr_wq
(Rob Millner)
- Fix a long standing double free OOPs, where a dynamically generated
'demo-mode' NodeACL has multiple sessions associated with it, and
the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables
demo-mode, but never converts the dynamic ACL into a explicit ACL
(Rob Millner)
- Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE
when the second phase WRITE COMMIT command fails, resulting in
CHECK_CONDITION response never being sent and se_cmd->cmd_kref
never reaching zero (Gary Guo)
Beyond these items on v4.1.y we've reproduced, fixed, and run through
our regression test suite using iscsi-target exports, there are two
additional outstanding list items:
- Remove a >= v4.2 RCU conversion BUG_ON that would trigger when
dynamic node NodeACLs where being converted to explicit NodeACLs.
The patch drops the BUG_ON to follow how pre RCU conversion worked
for this special case (Benjamin Estrabaud)
- Add ibmvscsis target_core_fabric_ops->max_data_sg_nent assignment
to match what IBM's Virtual SCSI hypervisor is already enforcing at
transport layer. (Bryant Ly + Steven Royer)"

The Generic PHY drivers gets assigned after we checked that the current
PHY driver is NULL, so we need to check a few things before we can
safely dereference d->driver. This would be causing a NULL deference to
occur when a system binds to the Generic PHY driver. Update
phy_attach_direct() to do the following:
- grab the driver module reference after we have assigned the Generic
PHY drivers accordingly, and remember we came from the generic PHY
path
- update the error path to clean up the module reference in case the
Generic PHY probe function fails
- split the error path involving phy_detacht() to avoid double free/put
since phy_detach() does all the clean up
- finally, have phy_detach() drop the module reference count before we
call device_release_driver() for the Generic PHY driver case

We'll OOPS in ramoops_get_next_prz() if the platform didn't ask for any
ftrace zones (i.e., cxt->fprzs will be NULL). Let's just skip this
entire FTRACE section if there's no 'fprzs'.

The nl80211_nan_dual_band_conf enumeration doesn't make much sense.
The default value is assigned to a bit, which makes it weird if the
default bit and other bits are set at the same time.
To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy
configuration to let the drivers define which bands are supported.
This is exposed to the userspace, which then can make a decision on
which band(s) to use. Additionally, rename all "dual_band" elements
to "bands", to make things clearer.

Without this change, the HDMI/DP codec will be recognised as a
generic codec, and there is no sound when playing through this codec.
As suggested by NVidia side, after adding the new ID in the driver,
the sound playing works well.

The IPIs come in as HVI not EE, so we need to test the appropriate
SRR1 bits. The encoding is such that it won't have false positives
on P7 and P8 so we can just test it like that. We also need to handle
the icp-opal variant of the flush.
