====================
net: stmmac: Fixes and Tegra186 support

This series of patches start with a few cleanups that I ran across while
adding Tegra186 support to the stmmac driver. It then adds code for FIFO
size parsing from feature registers and finally enables support for the
incarnation of the Synopsys DWC QOS IP found on NVIDIA Tegra186 SoCs.

This is based on next-20170310.

Changes in v2:
- address review comments by Mikko and Joao
- add two additional cleanup patches

net: stmmac: dwc-qos: Add Tegra186 support · e6ea2d16

Thierry Reding authored Mar 10, 2017

The NVIDIA Tegra186 SoC contains an instance of the Synopsys DWC
ethernet QOS IP core. The binding that it uses is slightly different
from existing ones because of the integration (clocks, resets, ...).

net: stmmac: dwc-qos: Split out ->probe() and ->remove() · cee45b2e

Thierry Reding authored Mar 10, 2017

Split out the binding specific parts of ->probe() and ->remove() to
enable the driver to support variants of the binding. This is useful in
order to keep backwards-compatibility while making it easy for a sub-
driver to deal only with the updated bindings rather than having to add
compatibility quirks all over the place.

net: stmmac: Parse FIFO sizes from feature registers · 11fbf811

Thierry Reding authored Mar 10, 2017

New version of this core encode the FIFO sizes in one of the feature
registers. Use these sizes as default, but still allow device tree to
override them for backwards compatibility.

When DMA mapping an SKB fragment, the mapping must be checked for
errors, otherwise the DMA debug code will complain upon unmap.

net: stmmac: Rename clk_ptp_ref clock to ptp_ref · 9fbb9dd8

Thierry Reding authored Mar 10, 2017

There aren't currently any users of the "clk_ptp_ref", but there are
other references to "ptp_ref", so I'm leaning towards considering that a
typo. Fix it.

vxlan: use appropriate family on L3 miss · 8f48ba71

Vincent Bernat authored Mar 10, 2017

When sending a L3 miss, the family is set to AF_INET even for IPv6. This
causes userland (eg "ip monitor") to be confused. Ensure we send the
appropriate family in this case. For L2 miss, keep using AF_INET.

====================
sctp: add receiver-side procedures for stream reconf asoc reset and add streams and response

Patch 2/7, 4/7, 5/7, 6/7 are to implement the process of asoc reset request,
add streams requests and all kinds of responses.

Patch 1/7 and 3/7 are ahead of 2/7 and 4/7 to add two event notification
for asoc reset and add streams.

Patch 7/7 is the last patch for implementing rfc6525 sctp stream reconf
to add sysctl and sockopt interface for users to enable sctp stream reconf.

After this patchset, sctp stream reconf will be able to work as rfc6525.

v1->v2:
  - put these into a smaller group.
  - rename the titles of the commits and improve some changelogs.
  - improve sctp_chunk_lookup_strreset_param and reuse it in patch 4/7.
  - process addstrm outreq as the ack of in addstrm inreq if strreset_chunk
    is not NULL in patch 4/7.
  - remove the stream alloc when sending addstrm inreq, and the process in
    peer will response it by sending a addstrm out request back in patch 5/7.
  - adjust the process of addstrm in resp to fit in the codes that only alloc
    streams through addstrm outreq in patch 6/7.
