eaabcd9e4e net: stmmac: dwxgmac2: Do not disable whole RX in dma_stop_rx()
We don't need to disable the whole RX when dma_stop_rx() is called
because there may be the need of just disabling 1 DMA channel.

This is also needed for stmmac Flow Control selftest.

091810dbde net: stmmac: Introduce selftests support
We add support for selftests on stmmac driver with 9 basic sanity checks
for now:
	- MAC Loopback
	- PHY Loopback
	- MMC Counters
	- EEE
	- Hash Filter Multicast
	- Perfect Filter Unicast
	- Multicast Filter All
	- Unicast Filter All
	- Flow Control

This allows for fast tracking of regressions in the driver and helps in
spotting mis-configuration of HW.

Changes from v1:
	- Fix build error as module (David)
	- Check for link status before running tests
Changes from RFC v2:
	- Return proper error code in stmmac_test_mmc (Corentin)
	- Use only 1 MMC counter in stmmac_test_mmc (Alexandre)
Changes from RFC v1:
	- Change test_loopback to test_mac_loopback (Andrew)
	- Change timeout to retries (Andrew)
	- Add MC/UC filter tests (Andrew)
	- Only test in offline mode (Andrew)
	- Do not call phy_loopback twice (Alexandre)

af5136f950 selftests/net: SO_TXTIME with ETF and FQ
The SO_TXTIME API enables packet tranmission with delayed delivery.
This is currently supported by the ETF and FQ packet schedulers.

Evaluate the interface with both schedulers. Install the scheduler
and send a variety of packets streams: without delay, with one
delayed packet, with multiple ordered delays and with reordering.
Verify that packets are released by the scheduler in expected order.

The ETF qdisc requires a timestamp in the future on every packet. It
needs a delay on the qdisc else the packet is dropped on dequeue for
having a delivery time in the past. The test value is experimentally
derived. ETF requires clock_id CLOCK_TAI. It checks this base and
drops for non-conformance.

The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP
as of commit fb420d5d91 ("tcp/fq: move back to CLOCK_MONOTONIC").
Within a flow there is an expecation of ordered delivery, as shown by
delivery times of test 4. The FQ qdisc does not require all packets to
have timestamps and does not drop for non-conformance.

The large (msec) delays are chosen to avoid flakiness.

	Output:

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:28 expected:0 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:38 expected:0 (us)

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:40 expected:0 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:33 expected:0 (us)

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:10120 expected:10000 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:10102 expected:10000 (us)

	[.. etc ..]

	OK. All tests passed

David Ahern says:

====================
ipv6: Move exceptions to fib6_nh and make it optional in a fib6_info

Patches 1 and 4 move pcpu and exception caches from fib6_info to fib6_nh.
With respect to the current FIB entries this is only a movement from one
struct to another contained within the first.

Patch 2 refactors the core logic of fib6_drop_pcpu_from into a helper
that is invoked per fib6_nh.

Patch 3 refactors exception handling in a similar way - creating a bunch
of helpers that can be invoked per fib6_nh with the goal of making patch
4 easier to review as well as creating the code needed for nexthop
objects.

Patch 5 makes a fib6_nh at the end of a fib6_info an array similar to
IPv4 and its fib_info. For the current fib entry model, all fib6_info
will have a fib6_nh allocated for it.

Patch 6 refactors ip6_route_del moving the code for deleting an
exception entry into a new function.

Patch 7 adds tests for redirect route exceptions. The new test was
written against 5.1 (before any of the nexthop refactoring). It and the
pmtu.sh selftest exercise the exception code paths - from creating
exceptions to cleaning them up on device delete. All tests pass without
any rcu locking or memleak warnings.

cc5c073a69 ipv6: Move exception bucket to fib6_nh
Similar to the pcpu routes exceptions are really per nexthop, so move
rt6i_exception_bucket from fib6_info to fib6_nh.

To avoid additional increases to the size of fib6_nh for a 1-bit flag,
use the lowest bit in the allocated memory pointer for the flushed flag.
Add helpers for retrieving the bucket pointer to mask off the flag.

The cleanup of the exception bucket is moved to fib6_nh_release.

fib6_nh_flush_exceptions can now be called from 2 contexts:
1. deleting a fib entry
2. deleting a fib6_nh

For 1., fib6_nh_flush_exceptions is called for a specific fib6_info that
is getting deleted. All exceptions in the cache using the entry are
deleted. For 2, the fib6_nh itself is getting destroyed so
fib6_nh_flush_exceptions is called for a NULL fib6_info which means
flush all entries.

The pmtu.sh selftest exercises the affected code paths - from creating
exceptions to cleaning them up on device delete. All tests pass without
any rcu locking or memleak warnings.

c0b220cf7d ipv6: Refactor exception functions
Before moving exception bucket from fib6_info to fib6_nh, refactor
rt6_flush_exceptions, rt6_remove_exception_rt, rt6_mtu_change_route,
and rt6_update_exception_stamp_rt. In all 3 cases, move the primary
logic into a new helper that starts with fib6_nh_. The latter 3
functions still take a fib6_info; this will be changed to fib6_nh
in the next patch.

In the case of rt6_mtu_change_route, move the fib6_metric_locked
out as a standalone check - no need to call the new function if
the fib entry has the mtu locked. Also, add fib6_info to
rt6_mtu_change_arg as a way of passing the fib entry to the new
helper.

No functional change intended. The goal here is to make the next
patch easier to review by moving existing lookup logic for each to
new helpers.

reference to the from entries that need to be evicted. If the passed

NULL are entries are flushed (e.g., fib6_nh is deleted).

For fib6_info entries with builtin fib6_nh (ie., current code) there
is no change in behavior.

f40b6ae2b6 ipv6: Move pcpu cached routes to fib6_nh
rt6_info are specific instances of a fib entry and are tied to a
device and gateway - ie., a nexthop. Before nexthop objects, IPv6 fib
entries have separate fib6_info for each nexthop in a multipath route,
so the location of the pcpu cache in the fib6_info struct worked.
However, with nexthop objects a fib6_info can point to a set of nexthops
(yet another alignment of ipv6 with ipv4). Accordingly, the pcpu
cache needs to be moved to the fib6_nh struct so the cached entries
are local to the nexthop specification used to create the rt6_info.

Initialization and free of the pcpu entries moved to fib6_nh_init and
fib6_nh_release.

Change in location only, from fib6_info down to fib6_nh; no other
functional change intended.

ENETC: support hardware timestamping

This patch-set is to support hardware timestamping for ENETC
and also to add ENETC 1588 timer device tree node for ls1028a.

Because the ENETC RX BD ring dynamic allocation has not been
supported and it is too expensive to use extended RX BDs
if timestamping is not used, a Kconfig option is used to
enable extended RX BDs in order to support hardware
timestamping. This option will be removed once RX BD
ring dynamic allocation is implemented.

d398231219 enetc: add hardware timestamping support
This patch is to add hardware timestamping support
for ENETC. On Rx, timestamping is enabled for all
frames. On Tx, we only instruct the hardware to
timestamp the frames marked accordingly by the stack.

Because the RX BD ring dynamic allocation has not been
supported and it is too expensive to use extended RX BDs
if timestamping is not used, a Kconfig option is used to
enable extended RX BDs in order to support hardware
timestamping. This option will be removed once RX BD
ring dynamic allocation is implemented.

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-05-23

This series contains updates to ice driver only.

Anirudh cleans up white space issues and other code formatting issues in the
driver.  Also implemented LLDP persistence across reboots and start/stop of the
LLDP agent.  Updated print statements for driver capabilities to include
if it is a device or function capability.

Bruce cleaned up variable declarations by removing unneeded assignment.

Dave fixes a potential hang due to a couple of flows that recursively
acquire the RTNL lock which results in a deadlock.

Tony updates the driver to advertise what link modes we are capable of
when the user does not request a specific link mode.

Usha fixes up the LLDP MIB change event handling by cleaning up
workarounds and print the DCB configuration changes detected.

Brett fixes the driver to handle failures in the VF reset path, which
was failing to free resources upon an error.

Richard fixed the reported of stats via ethtool to align with our other
Intel drivers.

Jesse optimizes the transmit buffer and ring structures to have more
efficient ordering to get hot cache lines to have packed data.  Also
optimized the VF structure to use less memory, since it is used hundreds
of times throughout the driver.

aa6ccf3f2d ice: Fix couple of issues in ice_vsi_release
Currently the driver is calling ice_napi_del() and then
unregister_netdev(). The call to unregister_netdev() will result in a
call to ice_stop() and then ice_vsi_close(). This is where we call
napi_disable() for all the MSI-X vectors. This flow is reversed so make
the changes to ensure napi_disable() happens prior to napi_del().

Before calling napi_del() and free_netdev() make sure
unregister_netdev() was called. This is done by making sure the
__ICE_DOWN bit is set in the vsi->state for the interested VSI.

72f9c20398 ice: Gracefully handle reset failure in ice_alloc_vfs()
Currently if ice_reset_all_vfs() fails in ice_alloc_vfs() we fail to
free some resources, reset variables, and return an error value.
Fix this by adding another unroll case to free the pf->vf array, set
the pf->num_alloc_vfs to 0, and return an error code.

Without this, if ice_reset_all_vfs() fails in ice_alloc_vfs() we will
not be able to do SRIOV without hard rebooting the system because
rmmod'ing the driver does not work.

function capabilities, and a "dev cap" prefix when printing device
capabilities.
