====================
net: stmmac: Improve mcast/ucast filter for snps

This patch series adds Synopsys specific bindings for the Synopsys EMAC
filter characteristics since those are implementation dependent. The
multicast and unicast filtering code was improved to handle different
configuration variations based on device tree settings.

I verified the operation of the multicast and unicast filters through
Synopsys support as requested during the V1 review, and tested the GMAC
configuration on an Altera Cyclone 5 SOC (which supports 256 multicast
bins and 128 Unicast addresses). The 10/100 variant of this driver
modification was not tested, although it was compile tested. I shared
the email thread results of the investigation through Synopsys with the
stmmac maintainer.

V4: Remove patch from series that addressed a sparse issue from a
    down rev'd version of sparse that does not show up in the
    latest version of sparse.
V3: Break up the patch into interface and functional change patches
    per review comments
V2: Confirm with Synopsys methods to determine number of Multicast bins
    and Unicast address filter entries per first round review comments.

      net: stmmac: Support devicetree configs for mcast and ucast filter entries · 3b57de95
      Vince Bridgers authored 
      This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case #8000684337 and shared with the maintainer.

      This patch adds socfpga Ethernet filter attributes for multicast
and unicast filters per Synopsys Ethernet IP configuration chosen
by Altera for the Cyclone 5 and Arria SOC FPGAs.

      dts: Add bindings for multicast hash bins and perfect filter entries · 94ceaa26
      Vince Bridgers authored 
      This change adds bindings for the number of multicast hash bins and perfect
filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is
configurable at device creation time, and can be configured for a different
number of multicast hash bins and a different number of perfect filter
entries. The device does not provide a way to query these parameters,
therefore parameters are required. The Altera Cyclone V SOC has support for
256 multicast hash bins and 128 perfect filter entries, and is different
than what's currently provided in the stmmac driver.

      net: stmmac: Correct set_filter for multicast and unicast cases · aefef4c1
      Vince Bridgers authored 
      This patch removes the check for the number of mulitcast addresses
when using hash based filtering since it's not necessary. If the number
of multicast addresses in the list exceeds the number of multicast hash
bins, the bins will "fold" over into one of the bins configured and
enabled for the particular component instance.

The default number of maximum unicast addresses was changed from 32 to 1
since this number is not dependent on the component revision. The maximum
number of multicast and unicast addresses is dependent on the configuration
of the Synopsys EMAC configured by the SOC architect at the time the
features were selected and configured for a particular component. Sadly,
Synopsys does not provide a way to query the precise number supported
by a particular component, so we must fall back on a devicetree entry.
This configuration could vary from vendor to vendor (such as STMicro,
Altera, etc).

The multicast bins are set for every possible filtering case (including
no entries) - previously the bits were set only if multicast filter entries
were present.

      net: stmmac: Change MAC interface to support multiple filter configurations · 7ed24bbe
      Vince Bridgers authored 
      The synopsys EMAC can be configured for different numbers of multicast hash
bins and perfect filter entries at device creation time and there's no way
to query this configuration information at runtime. As a result, a devicetree
parameter is required in order for the driver to program these filters
correctly for a particular device instance. This patch modifies the
10/100/1000 MAC software interface such that these configuration parameters
can be set at initialization time.

====================
Netfilter updates for net-next

The following patchset contains netfilter updates for net-next, they are:

1) Add the reject expression for the nf_tables bridge family, this
   allows us to send explicit reject (TCP RST / ICMP dest unrech) to
   the packets matching a rule.

2) Simplify and consolidate the nf_tables set dumping logic. This uses
   netlink control->data to filter out depending on the request.

3) Perform garbage collection in xt_hashlimit using a workqueue instead
   of a timer, which is problematic when many entries are in place in
   the tables, from Eric Dumazet.

4) Remove leftover code from the removed ulog target support, from
   Paul Bolle.

5) Dump unmodified flags in the netfilter packet accounting when resetting
   counters, so userspace knows that a counter was in overquota situation,
   from Alexey Perevalov.

6) Fix wrong usage of the bitwise functions in nfnetlink_acct, also from
   Alexey.

7) Fix a crash when adding new set element with an empty NFTA_SET_ELEM_LIST
   attribute.

This patchset also includes a couple of cleanups for xt_LED from
Duan Jiong and for nf_conntrack_ipv4 (using coccinelle) from
Himangi Saraogi.

      tcp: don't require root to read tcp_metrics · 388070fa
      Banerjee, Debabrata authored 
      commit d23ff701 (tcp: add generic netlink support for tcp_metrics) introduced
netlink support for the new tcp_metrics, however it restricted getting of
tcp_metrics to root user only. This is a change from how these values could
have been fetched when in the old route cache. Unless there's a legitimate
reason to restrict the reading of these values it would be better if normal
users could fetch them.
