Refactor igc_clean_rx_ring() helper, preparing the code for AF_XDP zero-copy support which is added by upcoming patches. The refactor consists of encapsulating page-shared specific code into its own helper, leaving common code that will be shared by both page-shared and xsk pool in igc_clean_rx_ring(). Signed-off-by:

Refactor __igc_xdp_run_prog() helper from igc_xdp_run_prog(), preparing the code for AF_XDP zero-copy support which is added by upcoming patches. The existing igc_xdp_run_prog() caters to regular XDP rx path which has to verify if bpf_prog is not NULL. Zero-copy path assumes that bpf_prog is not NULL and hence this check is not required. Therefore it makes sense to refactor the common code into a helper function, to avoid code duplication. Signed-off-by:

Move the helper igc_xdp_is_enabled() to igc_xdp.h so it can be reused in igc_xdp.c by upcoming patches that will introduce AF_XDP zero-copy support to the driver. Signed-off-by:

In case of error, the function mdiobus_get_phy() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Reported-by:

modern userspace applications, like OVN, can configure the TC datapath to "recirculate" packets several times. If more than 4 "recirculation" rules are configured, packets can be dropped by __tcf_classify(). Changing the maximum number of reclassifications (from 4 to 16) should be sufficient to prevent drops in most use cases, and guard against loops at the same time. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add support for new multipath hash policies This patchset adds support for two new multipath hash policies in mlxsw. Patch #1 emits net events whenever the net.ipv{4,6}.fib_multipath_hash_fields sysctls are changed. This allows listeners to react to changes in the packet fields used for the computation of the multipath hash. Patches #2-#3 refactor the code in mlxsw that is responsible for the configuration of the multipath hash, so that it will be easier to extend for the two new policies. Patch #4 adds the register fields required to support the new policies. Patch #5-#7 add support for inner layer 3 and custom multipath hash policies. Tested using following forwarding selftests: * custom_multipath_hash.sh * gre_custom_multipath_hash.sh * gre_inner_v4_multipath.sh * gre_inner_v6_multipath.sh ==================== -

When this policy is set, the kernel uses the inner layer 3 fields for multipath hash computation and falls back to the outer fields if no encapsulation was encountered. This behavior is most likely influenced by the behavior of the flow dissector, which is used for the packet dissection. The Spectrum ASIC, however, cannot fallback to outer fields if inner fields are not available. This should not result in a discrepancy from the software data path because if several flows have matching inner fields, they will tend to have matching outer fields as well. Therefore, implement this policy by enabling both outer and inner layer 3 fields for the multipath hash computation. Signed-off-by:

Currently, the multipath hash configuration is written directly to the register payload. While this is OK for the two currently supported policies, it is going to be hard to follow when more policies and more packet fields are added. Instead, set the required headers and fields in a bitmap and then dump it to the register payload. Signed-off-by:

The code was written when only two multipath hash policies were present, so the if statement was sufficient. The next patch and future patches are going to add support for more policies, so move to a switch statement. Signed-off-by:

Ido Schimmel authored
In-kernel notifications are already sent when the multipath hash policy itself changes, but not when the multipath hash fields change. Add these notifications, so that interested listeners (e.g., switch ASIC drivers) could perform the necessary configuration. Signed-off-by:

S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.
