MVPP2_TXQ_SCHED_TOKEN_CNTR_REG() expects the logical queue id but the current code is passing the global tx queue offset, so it ends up writing to unknown registers (between 0x8280 and 0x82fc, which seemed to be unused by the hardware).

Pull documentation fixes from Jonathan Corbet: "The Sphinx 2.0 release contained a few incompatible API changes that broke our extensions and, thus, the documentation build in general. Who knew that those deprecation warnings it was outputting actually meant we should change something? This set of fixes makes the build work again with Sphinx 2.0 and eliminates the warnings for 1.8. As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3. We will be adding some infrastructure soon to nudge users of old versions forward, with the idea of maybe increasing our minimum version (and removing this glue) sometime in the future" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations

2019-05-29net: sh_eth: fix mdio access in sh_eth_close() for R-Car Gen2 and RZ/A1 SoCsYoshihiro Shimoda
The sh_eth_close() resets the MAC and then calls phy_stop() so that mdio read access result is incorrect without any error according to kernel trace like below: ifconfig-216 [003] .n.. 109.133124: mdio_access: ee700000.ethernet-ffffffff read phy:0x01 reg:0x00 val:0xffff According to the hardware manual, the RMII mode should be set to 1 before operation the Ethernet MAC. However, the previous code was not set to 1 after the driver issued the soft_reset in sh_eth_dev_exit() so that the mdio read access result seemed incorrect. To fix the issue, this patch adds a condition and set the RMII mode register in sh_eth_dev_exit() for R-Car Gen2 and RZ/A1 SoCs. Note that when I have tried to move the sh_eth_dev_exit() calling after phy_stop() on sh_eth_close(), but it gets worse (kernel panic happened and it seems that a register is accessed while the clock is off).

2019-05-28net/mlx5e: Disable rxhash when CQE compress is enabledSaeed Mahameed
When CQE compression is enabled (Multi-host systems), compressed CQEs might arrive to the driver rx, compressed CQEs don't have a valid hash offload and the driver already reports a hash value of 0 and invalid hash type on the skb for compressed CQEs, but this is not good enough. On a congested PCIe, where CQE compression will kick in aggressively, gro will deliver lots of out of order packets due to the invalid hash and this might cause a serious performance drop. The only valid solution, is to disable rxhash offload at all when CQE compression is favorable (Multi-host systems).

2019-05-28net: stmmac: Do not output error on deferred probeThierry Reding
If the subdriver defers probe, do not show an error message. It's perfectly fine for this error to occur since the driver will get another chance to probe after some time and will usually succeed after all of the resources that it requires have been registered.

2019-05-27net: aquantia: tcp checksum 0xffff being handled incorrectlyNikita Danilov
Thats a known quirk in windows tcp stack it can produce 0xffff checksum. Thats incorrect but it is. Atlantic HW with LRO enabled handles that incorrectly and changes csum to 0xfffe - but indicates that csum is invalid. This causes driver to pass packet to linux networking stack with CSUM_NONE, stack eventually drops the packet. There is a quirk in atlantic HW to enable correct processing of 0xffff incorrect csum. Enable it. The visible bug is that windows link partner with software generated csums caused TCP connection to be unstable since all packets that csum value are dropped.

2019-05-27net: aquantia: fix LRO with FCS errorDmitry Bogdanov
Driver stops producing skbs on ring if a packet with FCS error was coalesced into LRO session. Ring gets hang forever. Thats a logical error in driver processing descriptors: When rx_stat indicates MAC Error, next pointer and eop flags are not filled. This confuses driver so it waits for descriptor 0 to be filled by HW. Solution is fill next pointer and eop flag even for packets with FCS error.

2019-05-27net: aquantia: check rx csum for all packets in LRO sessionDmitry Bogdanov
Atlantic hardware does not aggregate nor breaks LRO sessions with bad csum packets. This means driver should take care of that. If in LRO session there is a non-first descriptor with invalid checksum (L2/L3/L4), the driver must account this information in csum application logic.

2019-05-27net: aquantia: tx clean budget logic errorIgor Russkikh
In case no other traffic happening on the ring, full tx cleanup may not be completed. That may cause socket buffer to overflow and tx traffic to stuck until next activity on the ring happens. This is due to logic error in budget variable decrementor. Variable is compared with zero, and then post decremented, causing it to become MAX_INT. Solution is remove decrementor from the `for` statement and rewrite it in a clear way.
