40GbE Intel Wired LAN Driver Updates 2016-08-19
This series contains updates to i40e and i40evf only.
Jake provides several patches, first just moves a function to co-locate
the two functions related to configuring RSS via the admin queue, which
should help in spotting bugs when comparing the two functions. Fixed
an issue where commit e69ff813af35 ("i40e: rework the functions to
configure RSS with similar parameters") missed checking whether the seed
is NULL before using it and did not use the passed in *lut parameter.
Fixed an issue where a previous refactor missed i40e_vsi_config_rss()
and the values were being ignored, so checked for the fields and used
them instead of default values. Lastly replaced calls to
create_singlethread_workqueue() with alloc_workqueue() to provide more
control over workqueue creation and allows explicit setting of the
desired mode of operation.
Mitch adds link speed to log messages and reports speed through ethtool.
Carolyn refactors tail bump check and fixes byte ordering problems found
when enabling this feature support. Adds support for HMC resources and
profile commands for x722 firmware.
Heinrich Schuchardt fixes format identifiers from %u to %d since the
variable is defined as an integer.
Catherine fixes an issue where there was a race condition between the
completion of the client open and calls to the client ops, so ensured
that client ops are not called until we are sure client is open.
Harshitha makes sure that i40e_client_release() does not try to use
an adapter pointer which may not be initialized, so make sure it is.
Joe Perches fixes the use of the local macro XSTRINGIFY() to use
__stringify() instead.
Avinash corrects the mutex usage in client_subtask(). Fixed the RDMA
client to open again after reset since it is closed during a PF reset.
Jeff (me) clean up whitespace issues, where indentation was done
inconsistently and with spaces versus tabs.

ibmvnic: Handle backing device failover and reinitialization
An upcoming feature of IBM VNIC protocol is the ability to configure

will then wait for a message from the backing device before

====================
crypto/chcr: Add support for Chelsio Crypto Driver
This patch series adds support for Chelsio Crypto driver.
The patch series has been created against net-next tree and includes
patches for Chelsio Low Level Driver(cxgb4) and adds the new crypto
Upper Layer Driver(chcr) under a new directory drivers/crypto/chelsio.
Patch 1/4 ("cxgb4: Add support for dynamic allocation of resources for
ULD") adds support for dynamic allocation of resources for ULD. The
objective of this patch is to provide generic interface for upper layer
drivers to allocate and initialize hardware resources.
The present cxgb4 (network driver) apart from network functionality, also
initializes hardware and thus acts as lower layer driver for other drivers
to use hardware resources. Thus it acts as both a Low level driver for
Upper layer driver's like iw_cxgb4, cxgb4i and cxgb4it and a Network Driver.
Right now the allocation of resources for Upper layer driver's is done
statically. Patch 1/4 adds a new infrastructure for dynamic allocation of
resources. cxgb4 will read the hardware capability through firmware and
allocate/free the queues for Upper layer drivers when the respective
driver's are loaded and freed when unloaded.
Patch 2/3, 3/4 and 4/4 adds support for Chelsio Crypto Driver. The Crypto
driver will act as another ULD on top of cxgb4.
In this patch series, the ULD API framework is used only by crypto and other
ULD's will make use of it in the next series.
This patch series is only for review, if this looks ok we will test it
thoroughly and send request for merge.
We have included all the maintainers of respective drivers. Kindly
review the changes and provide feedback on the same.
V3: - Removed crypto queues from cxgb4 and added support for dynamic
allocation of resources for Upper layer drivers
- Dependency fix in Kconfig.
V2: - Some residual code cleanup
- Adds pr_fmt with chcr (KBUILD_MODNAME) added
- Changes var name to accomodate them <80 columns in the chcr_register_alg
- Support for printing the crypto queue stats
- Fix compile warnings reported by kbuild bot for certain architectures
- Dependency fix in Kconfig.
- If the request has the MAY_BACKLOG bit set and hardware queue is
full the request is queued up else -EBUSY is returned to throttle
the user. The queue when executed and processed returns -EINPROGRESS

tcp: refine tcp_prune_ofo_queue() to not drop all packets
Over the years, TCP BDP has increased a lot, and is typically
in the order of ~10 Mbytes with help of clever Congestion Control
modules.
In presence of packet losses, TCP stores incoming packets into an out of
order queue, and number of skbs sitting there waiting for the missing
packets to be received can match the BDP (~10 Mbytes)
In some cases, TCP needs to make room for incoming skbs, and current
strategy can simply remove all skbs in the out of order queue as a last
resort, incurring a huge penalty, both for receiver and sender.
Unfortunately these 'last resort events' are quite frequent, forcing
sender to send all packets again, stalling the flow and wasting a lot of
resources.
This patch cleans only a part of the out of order queue in order
to meet the memory constraints.

Use atomic bitwise operations when setting and checking reset
requests. This should help with possible races in the service task.

ixgbevf: only check Tx queue enablement when debugging
Following a write the VFTXDCTL.ENABLE bit is set only when the Tx queue
is actually enabled, which may not happen during the configure phase even
if we waited for it. Make this check debug only since this is causing
confusion with users who notice the warning in dmesg.

This patch is meant to allow for RX network flow classification to insert
and remove ethertype filter by ethtool
Example:
Add an ethertype filter:
$ ethtool -N eth0 flow-type ether proto 0x88F8 action 2
Show all filters:
$ ethtool -n eth0
4 RX rings available
Total 1 rules
Filter: 15
Flow Type: Raw Ethernet
Src MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
Dest MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
Ethertype: 0x88F8 mask: 0x0
Action: Direct to queue 2
Delete the filter by location:
$ ethtool -N delete 15

Merge branch 'qdisc-hash-fixes'
Jiri Kosina says:
====================
qdisc-hashtable fixes
The following two patches fix all the issues that have been reported
against the conversion of qdisc linked list to hashtable (currently in
net-next) so far.
First patch adjusts handling of singleton qdiscs to the new semantics, and
is rather straightforward.
The second patch, which fixes "cosmetic" issue of duplicate entries in the
qdisc dump for ingress qdiscs, is a little bit more hairy; I personally
would love to see all the already existing "if (ingress)"-like hacks go
away (by, let's say, introducing a general TCQ_F_? flag), but that's way
out of scope of this patchset (but already on my todo).
Thanks a lot to Daniel Borkmann and David Ahern for reporting the issues
and testing the patches promptly.
