      i40e: Record dma buffer info for dummy packets · 298deef1
      由 Anjali Singhai Jain 提交于 
      Save information that we can use while cleaning the tx ring. Also record
the time_stamp since we will need it to check tx hangs.

      net/mlx4_core: Warn if device doesn't have enough PCI bandwidth · b912b2f8
      由 Eyal Perry 提交于 
      Check if the device get enough bandwidth from the entire PCI chain to satisfy
its capabilities. This patch determines the PCIe device's bandwidth capabilities
by reading its PCIe Link Capabilities registers and then call the
pcie_get_minimum_link function to ensure that the adapter is hooked into a slot
which is capable of providing the necessary bandwidth capabilities.

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e only.

Anjali provides two cleanups to remove unnecessary code and a fix
to resolve debugfs dumping only half the NVM.  Then provides a fix
to ethtool NVM reads where shadow RAM was used instead of actual
NVM reads.

Jesse provides a couple of fixes, one removes custom i40e functions
which duplicate existing kernel functionality.  Second fixes constant
cast issues by replacing __constant_htons with htons.

Mitch provides a couple of fixes for the VF interfaces in i40e.  First
provides a fix to guard against VF message races with can cause a panic.
Second fix reinitializes the buffer size each time we clean the ARQ,
because subsequent messages can be truncated. Lastly adds functionality
to enable/disable ICR 0 dynamically.

Vasu adds a simple guard against multiple includes of the i40e_txrx.h
file.

Shannon provides a couple of fixes, first fix swaps a couple of lines
around in the error handling if the allocation for the VSI array fails.
Second fixes an issue where we try to free the q_vector that has not
been setup which can panic the kernel.

David provides a patch to save off the point to memory and the length
of 2 structs used in the admin queue in order to store all info about
allocated kernel memory.

Neerav fixes ring allocation where allocation and clearing of rings
for a VSI should be using the alloc_queue_pairs and not num_queue_pairs.
Then removes the unused define for multi-queue enabled.

      8021q: make vlan_pcpu_stats visible without CONFIG_VLAN_8021Q · 1e85c9b6
      由 Hannes Frederic Sowa 提交于 
      macvlan needs vlan_pcpu_stats so make it visible even if compiling
without VLAN_8021Q support. Otherwise a very long compiler error happens.

      net: netdev_kobject_init: annotate with __init · a48d4bb0
      由 Daniel Borkmann 提交于 
      netdev_kobject_init() is only being called from __init context,
that is, net_dev_init(), so annotate it with __init as well, thus
the kernel can take this as a hint that the function is used only
during the initialization phase and free up used memory resources
after its invocation.

====================
netfilter/IPVS updates for net-next

The following patchset contains Netfilter updates for your net-next tree,
they are:

* Add full port randomization support. Some crazy researchers found a way
  to reconstruct the secure ephemeral ports that are allocated in random mode
  by sending off-path bursts of UDP packets to overrun the socket buffer of
  the DNS resolver to trigger retransmissions, then if the timing for the
  DNS resolution done by a client is larger than usual, then they conclude
  that the port that received the burst of UDP packets is the one that was
  opened. It seems a bit aggressive method to me but it seems to work for
  them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a
  new NAT mode to fully randomize ports using prandom.

* Add a new classifier to x_tables based on the socket net_cls set via
  cgroups. These includes two patches to prepare the field as requested by
  Zefan Li. Also from Daniel Borkmann.

* Use prandom instead of get_random_bytes in several locations of the
  netfilter code, from Florian Westphal.

* Allow to use the CTA_MARK_MASK in ctnetlink when mangling the conntrack
  mark, also from Florian Westphal.

* Fix compilation warning due to unused variable in IPVS, from Geert
  Uytterhoeven.

* Add support for UID/GID via nfnetlink_queue, from Valentina Giusti.

* Add IPComp extension to x_tables, from Fan Du.
