      ipmr: remove hard code cache_resolve_queue_len limit · 0079ad8e
      Hangbin Liu authored 
      This is a re-post of previous patch wrote by David Miller[1].

Phil Karn reported[2] that on busy networks with lots of unresolved
multicast routing entries, the creation of new multicast group routes
can be extremely slow and unreliable.

The reason is we hard-coded multicast route entries with unresolved source
addresses(cache_resolve_queue_len) to 10. If some multicast route never
resolves and the unresolved source addresses increased, there will
be no ability to create new multicast route cache.

To resolve this issue, we need either add a sysctl entry to make the
cache_resolve_queue_len configurable, or just remove cache_resolve_queue_len
limit directly, as we already have the socket receive queue limits of mrouted
socket, pointed by David.

>From my side, I'd perfer to remove the cache_resolve_queue_len limit instead
of creating two more(IPv4 and IPv6 version) sysctl entry.

[1] https://lkml.org/lkml/2018/7/22/11
[2] https://lkml.org/lkml/2018/7/21/343

v3: instead of remove cache_resolve_queue_len totally, let's only remove
the hard code limit when allocate the unresolved cache, as Eric Dumazet
suggested, so we don't need to re-count it in other places.

v2: hold the mfc_unres_lock while walking the unresolved list in
queue_count(), as Nikolay Aleksandrov remind.

      hv_netvsc: Sync offloading features to VF NIC · 68622d07
      Haiyang Zhang authored 
      VF NIC may go down then come up during host servicing events. This
causes the VF NIC offloading feature settings to roll back to the
defaults. This patch can synchronize features from synthetic NIC to
the VF NIC during ndo_set_features (ethtool -K),
and netvsc_register_vf when VF comes back after host events.

      hv_netvsc: Allow scatter-gather feature to be tunable · b441f795
      Haiyang Zhang authored 
      In a previous patch, the NETIF_F_SG was missing after the code changes.
That caused the SG feature to be "fixed". This patch includes it into
hw_features, so it is tunable again.

1) Allover mlx5 cleanups

2) Added port congestion counters to ethtool stats:

Add 3 counters per priority to ethtool using PPCNT:
  2.1) rx_prio[p]_buf_discard - the number of packets discarded by device
       due to lack of per host receive buffers
  2.2) rx_prio[p]_cong_discard - the number of packets discarded by device
       due to per host congestion
  2.3) rx_prio[p]_marked - the number of packets ECN marked by device due
       to per host congestion

100GbE Intel Wired LAN Driver Updates 2019-09-05

This series contains updates to ice driver.

Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.

Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array.  Adds a pointer
check to prevent a NULL pointer dereference.  Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable.  Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s.  Updates the printed strings to make it
easier to search the logs for driver capabilities.

Jesse cleans up unnecessary function arguments.  Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.

Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.

Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.

Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.

Ashish updates the transmit context structure based on recent changes to
the hardware specification.

Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.
