Device statistics can be gathered on-demand. This adds the qed support for
reading the statistics [both function and port] from the device, and adds
to the public API a method for requesting the current statistics.

This adds basic link functionality to qede - driver still doesn't provide
users with an API to change any link property, but it does request qed to
initialize the link using default configuration, and registers a callback
that allows it to get link notifications.
This patch adds the ability of the driver to set the carrier as active and
to enable traffic as a result of async. link notifications.
Following this patch, driver should be capable of running traffic.

Physical link is handled by the management Firmware.
This patch lays the infrastructure for attention handling in the driver,
as link change notifications arrive via async. attentions,
as well the handling of such notifications.
This patch also extends the API with the protocol drivers by adding
registered callbacks which the protocol driver passes to qed in order
to be notified of async. events originating from the FW/HW.

This patch includes the basic Rx/Tx support for the driver [although
carrier will still never be turned on].
Following this patch the driver registers a network device, initializes

The Qlogic Everest Driver for Ethernet is the Ethernet specific module for
QL4xxx ethernet products by Qlogic.
This patch adds a very minimal PCI driver, one that doesn't yet register
a network device, but one that does interact with qed and does a basic
initialization of the HW.

This patch adds a public API for a network driver to work on top of QED.
The interface itself is very minimal - it's mostly infrastructure, as the
only content it has after this patch is a query for HW-based information
required for the creation of a network interface [I.e., no actual
protocol-specific configurations are supported].

The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
products by Qlogic.
This module serves two main purposes:
1. It's responsible to contain all the common code that will be shared
between the various drivers that would be used with said line of
products. Flows such as chip initialization and de-initialization
fall under this category.
2. It would abstract the protocol-specific HW & FW components, allowing
the protocol drivers to have a clean APIs which is detached in its
slowpath configuration from the actual HSI.
This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.

nf_ct_frag6_gather() makes a clone of each skb passed to it, and if the
reassembly is successful, expects the caller to free all of the original
skbs using nf_ct_frag6_consume_orig(). This call was previously missing,
meaning that the original fragments were never freed (with the exception
of the last fragment to arrive).
Fix this by ensuring that all original fragments except for the last
fragment are freed via nf_ct_frag6_consume_orig(). The last fragment
will be morphed into the head, so it must not be freed yet. Furthermore,
retain the ->next pointer for the head after skb_morph().

If ip_defrag() returns an error other than -EINPROGRESS, then the skb is
freed. When handle_fragments() passes this back up to
do_execute_actions(), it will be freed again. Prevent this double free
by never freeing the skb in do_execute_actions() for errors returned by
ovs_ct_execute. Always free it in ovs_ct_execute() error paths instead.

We were computing the child index in cases where the key value we were
looking for was actually less than the base key of the tnode. As a result
we were getting incorrect index values that would cause us to skip over
some children.
To fix this I have added a test that will force us to use child index 0 if
the key we are looking for is less than the key of the current tnode.

In commit b49a087("block: remove split code in
blkdev_issue_{discard,write_same}"), discard_granularity and alignment
checks were removed. Ideally, with bio late splitting, the upper layers
shouldn't need to depend on device's limits.
Christoph reported a discard regression on the HGST Ultrastar SN100 NVMe
device when mkfs.xfs. We have not found the root cause yet.
This patch re-adds discard_granularity and alignment checks by reverting
the related changes in commit b49a087. The good thing is now we can
remove the 2G discard size cap and just use UINT_MAX to avoid bi_size
overflow.

Jukka reported about the following warning:
"NOHZ: local_softirq_pending 08"
I remember this warning and we had a similar issue when using workqueues
and calling netif_rx. See commit 5ff3fec ("mac802154: fix NOHZ
local_softirq_pending 08 warning").
This warning occurs when calling "netif_rx" inside the wrong context
(non softirq context). The net core api offers "netif_rx_ni" to call
netif_rx inside the correct softirq context.

====================
This series includes code simplifaction. The main changes are the correct
xceiver handling (enable/disable) of the com20020 cards. The driver now handles
link status change detection. The EAE PCI-ARCNET cards now make use of the
rotary encoded subdevice indexing and got support for led triggers on transmit

Messages like "icmp6_send: no reply to icmp error" are close
to useless. Adding source and destination addresses to provide
some more clue.

Fix safety checks for bpf_perf_event_read():
- only non-inherited events can be added to perf_event_array map
(do this check statically at map insertion time)
- dynamically check that event is local and !pmu->count
Otherwise buggy bpf program can cause kernel splat.
Also fix error path after perf_event_attrs()
and remove redundant 'extern'.

In some cases low level drivers might want to update the
SPI transfer clock (e.g. during firmware download).
This patch adds this support. Without any modification the
driver will use the default SPI clock (from pdata or device tree).

Implement firmware download protocol for Marvell NFC controllers.
This protocol is based on NCI frames that's why parts of its
implementation use some NCI generic functions.

Add support for proprietary commands useful mainly
for factory testings.
Here is a list:
- FACTORY_MODE: Allow to set the driver into a mode where no
secure element are activated. It does not consider any
NFC_ATTR_VENDOR_DATA.
- HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
command. It does not consider any NFC_ATTR_VENDOR_DATA.
- HCI_DM_PUT_DATA: Allow to configure specific CLF registry as
for example RF trimmings or low level drivers configurations
(I2C, SPI, SWP).
- HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
CLF routing table following RF technology, CLF mode or protocol.
- HCI_DM_GET_INFO: Allow to retrieve CLF information.
- HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
low level drivers configurations or RF trimmings.
- HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete
packet can be more than 8KB.
- HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
configuration changes without CLF power off.
- HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
the white list).
- HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
technology. When using this command to anti-collision is done.
- HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
connectivity.
