In the case of internal reload (e.g., mtu change), there could be a race between link-up notification from mfw and the driver unload processing. In such case kernel assumes the link is up and starts using the queues which leads to the server crash. Send link notification to the kernel only when driver has already requested MFW for the link.

The values represented by qede->flags is being used in mixed ways: 1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage 2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS usage. This implementation pose problems in future when we want to add more flag values e.g., overlap of the values, overflow of 64-bit storage. Updated the implementation to go with approach (2) for qede->flags. Signed-off-by: -

MFW sends UFP notifications mostly during the device init phase and PFs might not be assigned with a name by this time. Hence capturing port-id in the debug messages would help in finding which PF the ufp notification was sent to. Also, fixed a minor scemantic issue in a debug print. Signed-off-by:

Igor Russkikh says: ==================== Add support for Aquantia AQtion USB to 5/2.5GbE devices This patchset introduces support for new multigig ethernet to USB dongle, developed jointly by Aquantia (Phy) and ASIX (USB MAC). The driver has similar structure with other ASIX MAC drivers (AX88179), but with a number of important differences: - Driver supports both direct Phy and custom firmware interface for Phy programming. This is due to different firmware modules available with this product. - Driver handles new 2.5G/5G link speed configuration and reporting. - Device support all speeds from 100M up to 5G. - Device supports MTU up to 16K. Device supports various standard networking features, like checksum offloads, vlan tagging/filtering, TSO. The code of this driver is based on original ASIX sources and was extended by Aquantia for 5G multigig support. Patchset v2 includes following changes: - Function variables declarions fixed to reverse xmass tree - Improve patch layout structure - Remove unnecessary curly braces in switch/case statements - Use 'packed' attribute for HW structures only - Use eth_mac_addr function in set_mac_addr callback - Remove unnecessary 'memset' calls. - Read MAC address from EEPROM function has now better name - Use driver_priv field to store context. It avoids ugly cast. - Set max_mtu field. Remove check for MTU size - Rewrite read/write functions. Add helpers for read/write 16/32 bit values - Use mask and shifts instead of bitfields to support BE platforms. - Use stack allocated buffer for configuring mcast filters - Use AUTONEG_ENABLE when go to suspend state - Pad out wol_cfg field from context structure. Use stack allocated instead - Remove driver version - Check field 'duplex' in set_link_ksetting callback as well - Use already created defines in usb matching macro - Rename phy_ops struct to phy_cfg - Use ether_addr_copy for copying mac address - Add fall-through comment in switch/case for avoid checkpatch warning - Remove match for CDC ether device - Add ASIX's HW id-s to match this driver - Add all HW id-s with which driver can work to blacklist of cdc_ether driver Patchset v3 includes following changes: - Use linkmode_copy instead of bitmap_copy - Remove Direct PHY access code since production HW will not have this mode anymore - Fix line over 80 symbols and alignments in cdc_ether patch - Add match for ECM configuration On start our HW reports both ECM and vendor configs. Linux prefers to use ECM driver and chooses active configuration which is for ecm driver (not for vendor specific). We need to match this configuration and forcibly switch configuration to vendor specific. Patchset v4 includes following changes: - Set gso_max_size. - Optimize accessing to descriptors - Use SKB_TRUESIZE macro. ==================== Signed-off-by: -

Ido Schimmel says: ==================== mlxsw: Prepare for VLAN-aware bridge w/VxLAN The driver is using 802.1Q filtering identifiers (FIDs) to represent the different VLANs in the VLAN-aware bridge (only one is supported). However, the device cannot assign a VNI to such FIDs, which prevents the driver from supporting the enslavement of VxLAN devices to the VLAN-aware bridge. This patchset works around this limitation by emulating 802.1Q FIDs using 802.1D FIDs, which can be assigned a VNI and so far have only been used in conjunction with VLAN-unaware bridges. The downside of this approach is that multiple {Port,VID}->FID entries are required, whereas a single VID->FID entry is required with "true" 802.1Q FIDs. First four patches introduce the new FID family of emulated 802.1Q FIDs and the associated type of router interfaces (RIFs). Last patch flips the driver to use this new FID family. The diff is relatively small because the internal implementation of each FID family is contained and hidden in spectrum_fid.c. Different internal users (e.g., bridge, router) are aware of the different FID types, but do not care about their internal implementation. This makes it trivial to swap the current implementation of 802.1Q FIDs with the new one, using 802.1D FIDs. ==================== Signed-off-by: -

Replace 802.1Q FIDs and VLAN RIFs with their emulated counterparts. The emulated 802.1Q FIDs are actually 802.1D FIDs and thus use the same flood tables, of per-FID type. Therefore, add 4K-1 entries to the per-FID flood tables for the new FIDs and get rid of the FID-offset flood tables that were used by the old 802.1Q FIDs. Signed-off-by:

Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of "VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of "FID" type. In other words, the RIF type is derived from the underlying FID type. VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on top of 802.1D FIDs. Since the previous patch emulated 802.1Q FIDs using 802.1D FIDs, this patch emulates VLAN RIFs using FID RIFs. Signed-off-by:

The driver uses 802.1Q FIDs when offloading a VLAN-aware bridge. Unfortunately, it is not possible to assign a VNI to such FIDs, which prompts the driver to forbid the enslavement of VxLAN devices to a VLAN-aware bridge. Workaround this hardware limitation by creating a new family of FIDs, emulated 802.1Q FIDs. These FIDs are emulated using 802.1D FIDs, which can be assigned a VNI. The downside of this approach is that multiple {Port, VID}->FID entries are required, whereas only a single VID->FID is required with "true" 802.1Q FIDs. Signed-off-by: -

802.1D FIDs use a per-FID flood table, where the flood index into the table is calculated by subtracting 4K from the FID's index. Currently, 802.1D FIDs start at 4K, so the calculation is correct, but if it was ever to change, the calculation will no longer be correct. In addition, this change will allow us to reuse the flood index calculation function in the next patch, where we are going to emulate 802.1Q FIDs using 802.1D FIDs. Signed-off-by:

When configuring an FDB entry pointing to a LAG netdev (or its upper), the driver should only set the 'lag_vid' field when the FID (filtering identifier) is of 802.1D type. Extend the 802.1D FID family with an attribute indicating whether this field should be set and based on its value set the field or leave it blank. Signed-off-by:

Nikolay Aleksandrov says: ==================== net: bridge: add an option to disabe linklocal learning This set adds a new bridge option which can control learning from link-local packets, by default learning is on to be consistent and avoid breaking users expectations. If the new no_linklocal_learn option is enabled then the bridge will stop learning from link-local packets. In order to save space for future boolean options, patch 01 adds a new bool option API that uses a bitmask to control boolean options. The bridge is by far the largest netlink attr user and we keep adding simple boolean options which waste nl attr ids and space. We're not directly mapping these to the in-kernel bridge flags because some might require more complex configuration changes (e.g. if we were to add the per port vlan stats now, it'd require multiple checks before changing value). Any new bool option needs to be handled by both br_boolopt_toggle and get in order to be able to retrieve its state later. All such options are automatically exported via netlink. The behaviour of setting such options is consistent with netlink option handling when a missing option is being set (silently ignored), e.g. when a newer iproute2 is used on older kernel. All supported options are exported via bm's optmask when dumping the new attribute. v2: address Andrew Lunn's comments, squash a minor change into patch 01, export all supported options via optmask when dumping, add patch 03, pass down extack so options can return meaningful errors, add WARN_ON on unsupported options (should not happen) ==================== Signed-off-by: -

Use the new boolopt API to add an option which disables learning from link-local packets. The default is kept as before and learning is enabled. This is a simple map from a boolopt bit to a bridge private flag that is tested before learning. v2: pass NULL for extack via sysfs Signed-off-by:
