Each CCP queue can product interrupts for 4 conditions:
operation complete, queue empty, error, and queue stopped.
This driver only works with completion and error events.

* A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".
* Replace the specification of a data structure by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.

Up to now, 'crypto_alloc_shash()' may return a valid pointer, an error
pointer or NULL (in case of invalid parameter)
Update it to always return an error pointer in case of error. It now
returns ERR_PTR(-EINVAL) instead of NULL in case of invalid parameter.
This simplifies error handling.
Also fix a crash in 'chcr_authenc_setkey()' if 'chcr_alloc_shash()'
returns an error pointer and the "goto out" path is taken.

Replace existing hw_ranndom/exynos-rng driver with a new, reworked one.
This is a driver for pseudo random number generator block which on
Exynos4 chipsets must be seeded with some value. On newer Exynos5420
chipsets it might seed itself from true random number generator block
but this is not implemented yet.
New driver is a complete rework to use the crypto ALGAPI instead of
hw_random API. Rationale for the change:
1. hw_random interface is for true RNG devices.
2. The old driver was seeding itself with jiffies which is not a
reliable source for randomness.
3. Device generates five random 32-bit numbers in each pass but old
driver was returning only one 32-bit number thus its performance was
reduced.
Compatibility with DeviceTree bindings is preserved.
New driver does not use runtime power management but manually enables
and disables the clock when needed. This is preferred approach because
using runtime PM just to toggle clock is huge overhead.
Another difference is reseeding itself with generated random data
periodically and during resuming from system suspend (previously driver
was re-seeding itself again with jiffies).

The patch fixes a critical issue to map txqid with flows on the hardware appropriately,
if tx queues created are more than flows configured then txqid shall map within
the range of hardware flows configured. This ensure that un-mapped txqid does not remain un-handled.

Add functionality for the VF to request up to 3 additional MAC filters.
This is done using existing E1000_VF_SET_MAC_ADDR message, but with
additional message info - E1000_VF_MAC_FILTER_CLR to clear all unicast
MAC filters previously set for this VF and E1000_VF_MAC_FILTER_ADD to
add MAC filter.
Additional filters can be added only in case if administrator did not
set VF MAC explicitly and allowed to change default MAC to the VF.
Due to the limited number of RAR entries reserve at least 3 MAC filters
for the PF.
If SRIOV is supported by the NIC after this change RAR entries starting
from 1 to (RAR MAX ENTRIES - NUM SRIOV VFS) will be used for PF and VF
MAC filters.

After an upgrade to Linux kernel v4.x the hardware timestamps of the
82579 Gigabit Ethernet Controller are different than expected.
The values that are being read are almost four times as big as before
the kernel upgrade.
The difference is that after the upgrade the driver sets the clock
frequency to 25MHz, where before the upgrade it was set to 96MHz. Intel
confirmed that the correct frequency for this network adapter is 96MHz.

I got a couple more reports: the Samsung APST issues appears to
affect multiple 950-series devices in Dell XPS 15 9550 and Precision
5510 laptops. Change the quirk: rather than blacklisting the
firmware on the first problematic SSD that was reported, disable
APST on all 144d:a802 devices if they're installed in the two
affected Dell models. While we're at it, disable only the deepest
sleep state instead of all of them -- the reporters say that this is
sufficient to fix the problem.
(I have a device that appears to be entirely identical to one of the
affected devices, but I have a different Dell laptop, so it's not
the case that all Samsung devices with firmware BXW75D0Q are broken
under all circumstances.)
Samsung engineers have an affected system, and hopefully they'll
give us a better workaround some time soon. In the mean time, this
should minimize regressions.

====================
10GbE Intel Wired LAN Driver Updates 2017-04-18
This series contains updates to mainly ixgbe with only one ixgbevf change.
Usha adds a check to ensure the creation of number of VF's is valid based
on the traffic classes configured, all to avoid transmit hangs.
Joe Perches reduces the use of pr_cont since the output can be interleaved
by other processes.
Tony cleans up the code overwriting the KX4 config, which is configured by
the NVM. Adds a check for MMNGC.MNG_VETO, to resolve an issue where we
were getting a link loss for the BMC when loading the driver.
Don fixes up SGMII x553 config details which were missed in earlier
implementations. Added support for x552 XFI backplane interface support.
Cleaned up an unused define, which was causing confusion on supported
devices.
Emil fixes a link issue on KR parts by making sure the default setting is
set. Refactors the code so that the code for allocating memory for the
list of MAC addresses that the VFs can use into its own function. Made
some code cleans to help readability and ensure notification of SRIOV
being enabled is done upon completion. Fixed an issue where if we failed
to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with
a NULL pointer dereference.
Philippe Reynes updates ixgbevf to use the new API for
{get|set}_link_ksettings.
Alex increases the headroom allocation when using build_skb() on a
system with 4K pages. Fixed an issue in ixgbe_dump() where we were no
longer clearing the status bit.

This patch is prompted by a static checker warning about a potential
use after free. The concern is that netif_rx_ni() can free "skb" and we
call it twice.
When I look at the commit that added this, it looks like some stray
lines were added accidentally. It doesn't make sense to me that we
would recieve the same data two times. I asked the author but never
recieved a response.
I can't test this code, but I'm pretty sure my patch is correct.

When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.
This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

So far, mlxsw_sp_port_vlan_set range is limited by
MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is
wrapped up by a helper function which actually does multiple calls
to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set
