Like the dsa_switch_tree structures, the dsa_port structures will be allocated on switch registration. The SJA1105 driver is the only one accessing the dsa_port structure after the switch allocation and before the switch registration. For that reason, move switch registration prior to assigning the priv member of the dsa_port structures.

The attempt to improve performance by changing the PCIe max read request size was added in the vendor driver more than 10 years back and copied to r8169 driver. In the vendor driver this has been removed long ago. Obviously it had no effect, also in my tests I didn't see any difference. Typically the max payload size is less than 512 bytes anyway, and the PCI core takes care that the maximum supported value is set.

2019-10-22mlxsw: core: Extend QSFP EEPROM size for ethtoolVadim Pasternak1-6/+17
Extend the size of QSFP EEPROM for the cable types SSF8436 and SFF8636 from 256 to 640 bytes in order to expose all the EEPROM pages by ethtool. For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of data for ethtool's get_module_eeprom() callback. This is because the driver uses the below defines to specify SFF module length in ethtool's get_module_info() callback: 'ETH_MODULE_SFF_8636_LEN' and 'ETH_MODULE_SFF_8436_LEN' (both are 256). As a result of exposing 256 bytes only, ethtool shows wrong "zero" info for pages 1, 2, 3. The patch changes the length returned by callback for get_module_info() to the values from the next defines: 'ETH_MODULE_SFF_8636_MAX_LEN' and 'ETH_MODULE_SFF_8436_MAX_LEN' (both are 640) to allow exposing of upper page 1, 2 and 3.

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2019-10-21 This series contains updates to e1000e and igc only. Sasha adds stream control transmission protocol (SCTP) CRC checksum support for igc. Also added S0ix support to the e1000e driver. Then added multicast support by adding the address list to the MTA table and providing the option for IPv6 address for igc. In addition, added receive checksum support to igc as well. Lastly, cleaned up some code that was not fully implemented yet for the VLAN filter table array. v2: Dropped patch 1 & 2 from the original series. Patch 1 is being sent to 'net' tree as a fix and patch 2 implementation needs to be re-worked. Updated the patch to add support for S0ix to fix the reverse Xmas tree issues and made the entry/exit functions void since they constantly returned success. All based on community feedback. v3: Cleaned up patch 4 of the series based on feedback from the community. Cleaned up a stray comma in a code comment and removed the 'inline' of a function that would be inlined by the compiler anyways. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>

Refactor mvneta_rx_swbm code introducing mvneta_swbm_rx_frame and mvneta_swbm_add_rx_fragment routines. Rely on build_skb in oreder to allocate skb since the previous patch introduced buffer recycling using the page_pool API. This patch fixes even an issue in the original driver where dma buffers are accessed before dma sync. mvneta driver can run on not cache coherent devices so it is necessary to sync DMA buffers before sending them to the device in order to avoid memory corruptions. Running perf analysis we can see a performance cost associated with this DMA-sync (anyway it is already there in the original driver code). In follow up patches we will add more logic to reduce DMA-sync as much as possible.

2019-10-19net: ethernet: dwmac-sun8i: show message only when switching to promiscMans Rullgard1-1/+2
Printing the info message every time more than the max number of mac addresses are requested generates unnecessary log spam. Showing it only when the hw is not already in promiscous mode is equally informative without being annoying. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: David S.

2019-10-19macb: propagate errors when getting optional clocksMichael Tretter1-6/+6
The tx_clk, rx_clk, and tsu_clk are optional. Currently the macb driver marks clock as not available if it receives an error when trying to get a clock. This is wrong, because a clock controller might return -EPROBE_DEFER if a clock is not available, but will eventually become available. In these cases, the driver would probe successfully but will never be able to adjust the clocks, because the clocks were not available during probe, but became available later. For example, the clock controller for the ZynqMP is implemented in the PMU firmware and the clocks are only available after the firmware driver has been probed. Use devm_clk_get_optional() in instead of devm_clk_get() to get the optional clock and propagate all errors to the calling function.

xenvif_connect_data() calls module_put() in case of error. This is wrong as there is no related module_get(). Remove the superfluous module_put().

2019-10-19net: hns3: fix mis-counting IRQ vector numbers issueYonglong Liu6-6/+58
Currently, the num_msi_left means the vector numbers of NIC, but if the PF supported RoCE, it contains the vector numbers of NIC and RoCE(Not expected). This may cause interrupts lost in some case, because of the NIC module used the vector resources which belongs to RoCE. This patch adds a new variable num_nic_msi to store the vector numbers of NIC, and adjust the default TQP numbers and rss_size according to the value of num_nic_msi.
