Make callers of nfp_net_ring_reconfig() pass newly allocated data path structure. We will gradually make use of that structure instead of passing parameters around to all the allocation functions. This commit adds allocation and propagation of new data path struct, no parameters are converted, yet. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

Joao Pinto says: ==================== prepare mac operations for multiple queues As agreed with David Miller, this patch-set is the first of 3 to enable multiple queues in stmmac. This first one concentrates on mac operations adding functionalities as: a) Configuration through DT b) RX and TX scheduling algorithms programming b) TX queues weight programming (essential in weightes algorithms) c) RX enable as DCB or AVB (preparing for future AVB support) d) Mapping RX queue to DMA channel e) IRQ treatment prepared for multiple queues f) Debug dump prepared for multiple queues g) CBS configuration In v3 patch-set version I included a new patch to enable CBS configuration (Patch 9). ==================== Signed-off-by: David S.

Thierry Reding says: ==================== 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 ==================== Signed-off-by: David S.

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, ...). Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

Xin Long says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patchset is to add SCTP_RECONFIG_SUPPORTED sockopt, it would set and get asoc reconf_enable value when asoc_id is set, or it would set and get ep reconf_enalbe value if asoc_id is 0. It is also to add sysctl interface for users to set the default value for reconf_enable. After this patch, stream reconf will work.

This patch is to implement Receiver-Side Procedures for the Re-configuration Response Parameter in rfc6525 section 5.2.7. sctp_process_strreset_resp would process the response for any kind of reconf request, and the stream reconf is applied only when the response result is success.
