Some sky2 chips fire IRQ after S3, before the driver is fully resumed:
[ 686.804877] do_IRQ: 1.37 No irq handler for vector

This is likely a platform bug that device isn't fully quiesced during
S3. Use MSI-X, maskable MSI or INTx can prevent this issue from
happening.

Since MSI-X and maskable MSI are not supported by this device, fallback
to use INTx on affected platforms.

Devlink health updates

This patchset includes a fix [patch 01] to the devlink health state update, in
case recover was aborted.

In addition, it includes a small enhancement to the infrastructure in order to
allow direct state update in run-time, and use it from mlx5e tx reporter.

Once channels were successfully opened, update tx reporter health state to
healthy. This is needed for the following scenario:
- SQ has an un-recovered error reported to the devlink health, resulting tx
  reporter state to be error.
- Current channels (including this SQ) are closed
- New channels are opened
After that flow, the original error was "solved", and tx reporter state
should be healthy. However, as it was resolved as a side effect, and not
via tx reporter recover method, driver needs to inform devlink health
about it.

It is possible that a reporter state will be updated due to a recover flow
which is not triggered by a devlink health related operation, but as a side
effect of some other operation in the system.

Expose devlink health API for a direct update of a reporter status.

Move devlink_health_reporter_state enum definition to devlink.h so it could
be used from drivers as a parameter of devlink_health_reporter_state_update.

In addition, add trace_devlink_health_reporter_state_update to provide user
notification for reporter state change.

If devlink_health_report() aborted the recover flow due to grace period checker,
it left the reporter status as DEVLINK_HEALTH_REPORTER_STATE_HEALTHY, which is
a bug. Fix that by always setting the reporter state to
DEVLINK_HEALTH_REPORTER_STATE_ERROR prior to running the checker mentioned above.

In addition, save the previous health_state in a temporary variable, then use
it in the abort check comparison instead of using reporter->health_state which
might be already changed.

Similar to commit 44f49dd8 ("ipmr: fix possible race resulting from
improper usage of IP_INC_STATS_BH() in preemptible context."), we cannot
assume preemption is disabled when incrementing the counter and
accessing a per-CPU variable.

Preemption can be enabled when we add a route in process context that
corresponds to packets stored in the unresolved queue, which are then
forwarded using this route [1].

Fix this by using IP6_INC_STATS() which takes care of disabling
preemption on architectures where it is needed.

pull-request: bpf-next 2019-03-04

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add AF_XDP support to libbpf. Rationale is to facilitate writing
   AF_XDP applications by offering higher-level APIs that hide many
   of the details of the AF_XDP uapi. Sample programs are converted
   over to this new interface as well, from Magnus.

2) Introduce a new cant_sleep() macro for annotation of functions
   that cannot sleep and use it in BPF_PROG_RUN() to assert that
   BPF programs run under preemption disabled context, from Peter.

3) Introduce per BPF prog stats in order to monitor the usage
   of BPF; this is controlled by kernel.bpf_stats_enabled sysctl
   knob where monitoring tools can make use of this to efficiently
   determine the average cost of programs, from Alexei.

4) Split up BPF selftest's test_progs similarly as we already
   did with test_verifier. This allows to further reduce merge
   conflicts in future and to get more structure into our
   quickly growing BPF selftest suite, from Stanislav.

5) Fix a bug in BTF's dedup algorithm which can cause an infinite
   loop in some circumstances; also various BPF doc fixes and
   improvements, from Andrii.

6) Various BPF sample cleanups and migration to libbpf in order
   to further isolate the old sample loader code (so we can get
   rid of it at some point), from Jakub.

7) Add a new BPF helper for BPF cgroup skb progs that allows
   to set ECN CE code point and a Host Bandwidth Manager (HBM)
   sample program for limiting the bandwidth used by v2 cgroups,
   from Lawrence.

8) Enable write access to skb->queue_mapping from tc BPF egress
   programs in order to let BPF pick TX queue, from Jesper.

9) Fix a bug in BPF spinlock handling for map-in-map which did
   not propagate spin_lock_off to the meta map, from Yonghong.

10) Fix a bug in the new per-CPU BPF prog counters to properly
    initialize stats for each CPU, from Eric.

11) Add various BPF helper prototypes to selftest's bpf_helpers.h,
    from Willem.

12) Fix various BPF samples bugs in XDP and tracing progs,
    from Toke, Daniel and Yonghong.

13) Silence preemption splat in test_bpf after BPF_PROG_RUN()
    enforces it now everywhere, from Anders.

14) Fix a signedness bug in libbpf's btf_dedup_ref_type() to
    get error handling working, from Dan.

15) Fix bpftool documentation and auto-completion with regards
    to stream_{verdict,parser} attach types, from Alban.

mlxsw: minimal: Add ethtool and resource query support

Vadim says:

The minimal driver is chip independent and uses I2C bus for chip access.
Its purpose is to support chassis management on systems equipped with
Mellanox switch ASICs. For example, from a BMC (Board Management
Controller) device.

Patches #1-#3 add ethtool support to the minimal driver so that QSFP/SFP
module info could be retrieved by the driver. This is done by exposing a
dummy netdev for each front panel port and implementing the required
ethtool operations.

Patches #4-#8 add resource query support. This allows the driver to
query the firmware about values of certain resources (e.g., maximum
number of ports). It is required on systems where the maximum number of
ports is larger than the hard coded default (64).

Today, tls_sw_recvmsg is capable of using asynchronous mode to handle
application data TLS records. Moreover, it assumes that if the cipher
can be handled asynchronously, then all packets will be processed
asynchronously.

However, this assumption is not always true. Specifically, for AES-GCM
in TLS1.2, it causes data corruption, and breaks user applications.

This patch fixes this problem by separating the async capability from
the decryption operation result.

Make logging of an ethernet address more consistent with

The %02hx use also did not quite match the u8 definition
of addr though that did not actually matter given normal

We were skipping the prepare phase which causes some problems with at
least a couple of drivers:

- mv88e6xxx chooses to skip programming VID = 0 with -EOPNOTSUPP in
  the prepare phase, but we would still try to force this VID since we
  would only call the commit phase and so we would get the driver to
  return -EINVAL instead

- qca8k does not currently have a port_vlan_add() callback implemented,
  yet we would try to call that unconditionally leading to a NPD

Fix both issues by conforming to the current model doing a
prepare/commit phase, this makes us consistent throughout the code and
assumptions.
