This reverts commit aeeecb88. The new SNMP variable (TCPSmallQueueFailure) can be incremented for good reasons, even on a 100Gbit single TCP_STREAM flow. If we really wanted to ease driver debugging [1], this would require something more sophisticated. [1] Usually, if a driver is delaying TX completions too much, this can lead to stalls in TCP output. Various work arounds have been used in the past, like skb_orphan() in ndo_start_xmit().

Russell King says: ==================== net: dsa: convert two drivers to phylink_generic_validate() Patches 1 to 3 update core DSA code to allow drivers to be converted, and patches 4 and 5 convert hellcreek and lantiq to use this (both of which received reviewed-by from their maintainers.) As the rest have yet to be reviewed by their maintainers, they are not included here. Patch 1 had a request to change the formatting of it; I have not done so as I believe a patch should do one change and one change only - reformatting it is a separate change that should be in its own patch. However, as patch 2 gets rid of the reason for reformatting it, it would be pointless, and pure noise to include such an intermediary patch. Instead, I have swapped the order of patches 2 and 3 from the RFC series. ==================== Link: https://lore.kernel.org/r/YaYiiU9nvmVugqnJ@shell.armlinux.org.ukSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Populate the supported interfaces and MAC capabilities for the Lantiq DSA switches and remove the old validate implementation to allow DSA to use phylink_generic_validate() for this switch driver. The exclusion of Gigabit linkmodes for MII, Reverse MII and Reduced MII links is handled within phylink_generic_validate() in phylink, so there is no need to make them conditional on the interface mode in the driver.

The switch actually only supports MII and RGMII, but as phylib defaults to GMII, we need to include this interface mode to keep existing DT working.

Support the use of phylink_generic_validate() when there is no phylink_validate method given in the DSA switch operations and mac_capabilities have been set in the phylink_config structure by the DSA switch driver. This gives DSA switch drivers the option to use this if they provide the supported_interfaces and mac_capabilities, while still giving them an option to override the default implementation if necessary.

Phylink needs slightly more information than phylink_get_interfaces() allows us to get from the DSA drivers - we need the MAC capabilities.

No concurrent access is possible when a bitmap is local to a function. So prefer the non-atomic functions to save a few cycles. - replace a 'for' loop by an equivalent non-atomic 'bitmap_fill()' call - use '__set_bit()' While at it, clear the 'bitmask' bitmap only when needed.

From: Ido Schimmel <idosch@nvidia.com> ==================== mlxsw: Spectrum-4 preparations The Spectrum-4 ASIC will support more than 256 ports, unlike existing ASICs. As such, various device registers were extended with two additional bits to encode a 10 bit local port. In some cases, new (Version 2) registers were introduced. This patchset prepares mlxsw for Spectrum-4 support by encoding local port in a 'u16' instead of a 'u8' and by extending the definitions of the various registers to support the extended local port form. ==================== Signed-off-by: David S.

Add 'port_page' field in SBSR to be able to query occupancy of more than 256 ports. The field determines the range of the ports specified in the 'ingress_port_mask' and 'egress_port_mask' bit masks: >From '256 * port_page' to '256 * port_page + 255'. For each local port, the appropriate port page is used. A query is never performed for a port range that spans multiple port pages.

Local port 255 has a special meaning in PPCNT register, it is used to refer to all local ports. This wild card ability is not currently used by the driver. Special casing local port 255 in Spectrum-4 systems where it is a valid port is going to be a problem. Work around this issue by adding and always setting the 'lp_gl' bit which instructs the device's firmware to treat this local port like an ordinary port.

Currently, local_port field uses 8 bits, which means that maximum 256 ports can be used. As preparation for the next ASIC, which will support more than 256 ports, local_port field should be extended to 10 bits. It is not possible to use 10 consecutive bits in all registers, and therefore, the field is split into 2 fields: 1. local_port - the existing 8 bits, represent LSB of the extended field. 2. lp_msb - extra 2 bits, represent MSB of the extended field. To avoid complex programming when reading/writing local_port, add a dedicated macro which creates get and set functions which handle both parts of local_port.
