Pablo Neira Ayuso 502061f81d netfilter: nf_tables: add packet duplication to the netdev family
You can use this to duplicate packets and inject them at the egress path
of the specified interface. This duplication allows you to inspect
traffic from the dummy or any other interface dedicated to this purpose.

can match packets over the ratelimit. This is required to support what

Pablo Neira Ayuso f4c756b4ea netfilter: nf_tables: remove check against removal of inactive objects
The following sequence inside a batch, although not very useful, is
valid:

 add table foo
 ...
 delete table foo

This may be generated by some robot while applying some incremental
upgrade, so remove the defensive checks against this.

This patch keeps the check on the get/dump path by now, we have to
replace the inactive flag by introducing object generations.

Pablo Neira Ayuso df05ef874b netfilter: nf_tables: release objects on netns destruction
We have to release the existing objects on netns removal otherwise we
leak them. Chains are unregistered in first place to make sure no
packets are walking on our rules and sets anymore.

The object release happens by when we unregister the family via
nft_release_afinfo() which is called from nft_unregister_afinfo() from
the corresponding __net_exit path in every family.

Michael Chan b72d4a68c4 bnxt_en: Keep track of the ring group resource.
Newer firmware will return the ring group resource when we call
hwrm_func_qcaps().  To be compatible with older firmware, use the
number of tx rings as the number of ring groups if the older firmware
returns 0.  When determining how many rx rings we can support, take
the ring group resource in account as well in _bnxt_get_max_rings().
Divide and assign the ring groups to VFs.

Michael Chan 4a21b49b34 bnxt_en: Improve VF resource accounting.
We need to keep track of all resources, such as rx rings, tx rings,
cmpl rings, rss contexts, stats contexts, vnics, after we have
divided them for the VFs.  Otherwise, subsequent ring changes on
the PF may not work correctly.

We adjust all max resources in struct bnxt_pf_info after they have been
assigned to the VFs.  There is no need to keep the separate
max_pf_tx_rings and max_pf_rx_rings.

When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the
max resources for the PF.

Michael Chan 2bcfa6f6e7 bnxt_en: Check hardware resources before enabling NTUPLE.
The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured.  We need to make sure we have the
resources before we enable NTUPLE.  Add bnxt_rfs_capable() to do the
checking.

In addition, we need to do the same checking in ndo_fix_features().  As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.

Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem.  To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

Freescale DPAA FMan

The Freescale Data Path Acceleration Architecture (DPAA) is a set
of hardware components on specific QorIQ multicore processors.
This architecture provides the infrastructure to support
simplified sharing of networking interfaces and accelerators
by multiple CPU cores and the accelerators.

One of the DPAA accelerators is the Frame Manager (FMan)
which contains a series of hardware blocks: ports, Ethernet MACs,
a multi user RAM (MURAM) and Storage Profile (SP).

This patch set introduce the FMan drivers.
Each driver configures and initializes the corresponding
FMan hardware module (described above).
The MAC driver offers support for three different
types of MACs (eTSEC, TGEC, MEMAC).

Andrew Lunn f5e2ed022d dsa: mv88e6xxx: Add Second back of statistics
The 6320 family of switch chips has a second bank for statistics, but
is missing three statistics in the port registers. Generalise and
extend the code:

* adding a field to the statistics table indicating the bank/register
  set where each statistics is.
* add a function indicating if an individual statistics
  is available on this device
* calculate at run time the sset_count.
* return strings based on the available statistics of the device
* return statistics based on the available statistics of the device
* Add support for reading from the second bank.

David S. Miller ff5756d0d3 Merge branch 'sfc-vf'
Bert Kenward says:

====================
sfc: additional virtual function support​

This introduces the client side of a mechanism to defer authorisation of
operations, for example multicast subscription. Although primarily aimed at
SRIOV VFs this can also apply to unprivileged PFs.

Also handle reboot ordering corner cases better and reduce the level of some
logging.

v2: remove #ifdef DEBUG around new WARN_ON in mcdi.c.

Bert Kenward 09a04204f0 sfc: Downgrade or remove some error messages
Depending on configuration the NIC may return errors for unprivileged
functions and/or VFs. Where these are expected and handled, reduce the
level of any output.
