Add a list of switch ports within the switch fabric. This will help the lookup of a port inside the whole fabric, and it is the first step towards supporting multiple CPU ports, before deprecating the usage of the unique dst->cpu_dp pointer. In preparation for a future allocation of the dsa_port structures, return -ENOMEM in case no structure is returned, even though this error cannot be reached yet.

Do not let the drivers access the ds->ports static array directly while there is a dsa_to_port helper for this purpose. At the same time, un-const this helper since the SJA1105 driver assigns the priv member of the returned dsa_port structure.

Heiner Kallweit says: ==================== 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. So let's remove fiddling with PCIe max read request size from r8169 too. This change allows to simplify the driver in the subsequent three patches of this series. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>

With the introduction of the link group termination worker there is no longer a need to postpone smc_close_active_abort() to a worker.

Locking hierarchy requires that the link group conns_lock can be taken if the socket lock is held, but not vice versa. Nevertheless socket termination during abnormal link group termination should be protected by the socket lock.

Ido Schimmel says: ==================== Vadim says: This patch set extends the size of QSFP EEPROM for the cable types SSF-8436 and SFF-8636 from 256 bytes to 640 bytes. This allows ethtool to show correct information for these cable types (more details below). Patch #1 adds a macro that computes the EEPROM page number from the provided offset specified in the request. Patch #2 teaches the driver to access the information stored in the upper pages of the QSFP memory map. Details and examples: SFF-8436 specification defines pages 0, 1, 2 and 3. Page 0 contains lower memory page offsets (from 0x00 to 0x7f) and upper page offsets (from 0x80 to 0xfe). Upper pages 1, 2 and 3 are optional and can be empty. Page 1 is provided if upper page 0 byte 0xc3 bit 6 is set. Page 2 is provided if upper page 0 byte 0xc3 bit 7 is set. Page 3 is provided if lower page 0 byte 0x02 bit 2 is cleared. Offset 0xc3 for the upper page is provided as 0x43 = 0xc3 - 0x80. As a result of exposing 256 bytes only, ethtool shows wrong information for pages 1, 2 and 3. In the below hex dump from ethtool for a cable compliant to SFF-8636 specification, it can be seen that EEPROM of this device contains optical diagnostic page (lower page 0 byte 0x02 bit 2 is cleared), but it is not exposed, as the length defined for this type is 256 bytes. $ ethtool -m sfp42 hex on Offset Values ------ ------ 0x0000: 11 07 00 ff 00 ff 00 00 00 55 55 00 00 00 00 00 0x0010: 00 00 00 00 00 00 2a 90 00 00 82 ae 00 00 00 00 0x0020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0050: 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 0x0060: 00 00 ff 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0070: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0080: 11 8c 0c 80 00 00 00 00 00 00 00 05 ff 00 00 23 0x0090: 00 00 32 00 4d 65 6c 6c 61 6e 6f 78 20 20 20 20 0x00a0: 20 20 20 20 00 00 02 c9 4d 4d 41 31 42 30 30 2d 0x00b0: 53 53 31 20 20 20 20 20 41 32 42 68 0b b8 46 05 0x00c0: 02 07 f5 9e 4d 54 31 38 33 34 46 54 30 33 38 34 0x00d0: 36 20 20 20 31 38 30 37 30 33 00 00 0c 10 67 c2 0x00e0: 38 32 36 46 4d 41 32 32 36 49 30 31 31 35 20 20 0x00f0: 00 00 00 00 00 00 00 00 00 00 01 00 0e 00 00 00 After changing the length returned by get_module_info() callback from 256 bytes to 640 bytes, the upper pages 1, 2 and 3 are exposed by ethtool.

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.

Support the firmware of PHY NC which is used to fix the issue found for PHY. Currently, only RTL_VER_04, RTL_VER_05, and RTL_VER_06 need it. The order of loading PHY firmware would be RTL_FW_PHY_START RTL_FW_PHY_NC RTL_FW_PHY_STOP The RTL_FW_PHY_START/RTL_FW_PHY_STOP are used to lock/unlock the PHY, and set/clear the patch key from the firmware file.

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>

Heiner Kallweit says: ==================== net: phy: marvell: support downshift as PHY tunable So far downshift is implemented for one small use case only and can't be controlled from userspace. So let's implement this feature properly as a PHY tunable so that it can be controlled via ethtool. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Instead of superseded function marvell_set_downshift() we can use new function m88e1111_set_downshift() in m88e1116r_config_init(). For this m88e1116r_config_init() has to be moved in the code.

So far downshift is implemented for one small use case only and can't be controlled from userspace. So let's implement this feature properly as a PHY tunable so that it can be controlled via ethtool. More Marvell PHY's may support downshift, but I restricted it for now to the ones where I have the datasheet. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

Lorenzo Bianconi says: ==================== add XDP support to mvneta driver Add XDP support to mvneta driver for devices that rely on software buffer management. Supported verdicts are: - XDP_DROP - XDP_PASS - XDP_REDIRECT - XDP_TX Moreover set ndo_xdp_xmit net_device_ops function pointer in order to support redirecting from other device (e.g. virtio-net). Convert mvneta driver to page_pool API. This series is based on previous work done by Jesper and Ilias. We will send follow-up patches to reduce DMA-sync operations. Changes since v4: - reset page_pool pointer to NULL in mvneta_rxq_drop_pkts and in mvneta_create_page_pool error path - move dma sync in mvneta_rx_refill() in patch 2/7 - verify bpf prog pointer in mvneta_xdp_setup to double-check if stop/start is really necessary - coding style fixes Changes since v3: - rename MVNETA_XDP_CONSUMED in MVNETA_XDP_DROPPED - squash patch 4/8 and patch 3/8 - fix dma sync for XDP_TX verdict - fix queue_index in xdp_rxq_info_reg - cosmetics Changes since v2: - rely on page_pool_recycle_direct instead of xdp_return_buff for XDP_DROP - define xdp buffer in mvneta_rx_swbm and avoid default initializations - use dma_sync_single_for_cpu instead of dma_sync_single_range_for_cpu - run page_pool_release_page in mvneta_swbm_add_rx_fragment even if the buffer contains just ETH_FCS Changes since v1: - sync dma buffers before refilling hw queues - fix stats accounting Changes since RFC: - implement XDP_TX - make tx pending buffer list agnostic - code refactoring - check if device is running in mvneta_xdp_setup ==================== Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.
