2024-01-03net: ena: Refactor napi functionsDavid Arinzon
This patch focuses on changes to the XDP part of the napi polling routine. 1. Update the `napi_comp` stat only when napi is actually complete. 2. Simplify the code by using a function pointer to the right napi routine (XDP vs non-XDP path) 3. Remove unnecessary local variables. 4. Adjust a debug print to show the processed XDP frame index rather than the pointer.

This check is already done in ena_clean_rx_irq() which indirectly calls it.

2024-01-03net: ena: Use tx_ring instead of xdp_ring for XDP channel TXDavid Arinzon
When an XDP program is loaded the existing channels in the driver split into two halves: - The first half of the channels contain RX and TX rings, these queues are used for receiving traffic and sending packets originating from kernel. - The second half of the channels contain only a TX ring. These queues are used for sending packets that were redirected using XDP_TX or XDP_REDIRECT. Referring to the queues in the second half of the channels as "xdp_ring" can be confusing and may give the impression that ENA has the capability to generate an additional special queue. This patch ensures that the xdp_ring field is exclusively used to describe the XDP TX queue that a specific RX queue needs to utilize when forwarding packets with XDP TX and XDP REDIRECT, preserving the integrity of the xdp_ring field in ena_ring.

2024-01-03net: ena: Introduce total_tx_size field in ena_tx_buffer structDavid Arinzon
To avoid de-referencing skb or xdp_frame when we poll for TX completion (where they might not be in the cache), save the total TX packet size in the ena_tx_buffer object representing the packet. Also the 'print_once' field's type was changed from u32 to u8 to allow adding the 'total_tx_size' without changing the total size of the struct.

2024-01-03net: ena: Put orthogonal fields in ena_tx_buffer in a unionDavid Arinzon
The skb and xdpf pointers cannot be set together in the driver (each TX descriptor can send either an SKB or an XDP frame), and so it makes more sense to put them both in a union. This decreases the overall size of the ena_tx_buffer struct which improves cache locality.

2024-01-03net: ena: Pass ena_adapter instead of net_device to ena_xmit_common()David Arinzon
This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints.

XDP system has a very large footprint in the driver's overall code. makes the whole driver's code much harder to read. Moving XDP code to dedicated files. This patch doesn't make any changes to the code itself and only cut-pastes the code into ena_xdp.c and ena_xdp.h files so the change is purely cosmetic.

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2]) have a /bin/sh shebang which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash.

2024-01-03net/sched: cls_api: complement tcf_tfilter_dump_policyLin Ma
In function `tc_dump_tfilter`, the attributes array is parsed via tcf_tfilter_dump_policy which only describes TCA_DUMP_FLAGS. However, the NLA TCA_CHAIN is also accessed with `nla_get_u32`. The access to TCA_CHAIN is introduced in commit 5bc1701881e3 ("net: sched: introduce multichain support for filters") and no nla_policy is provided for parsing at that point. Later on, tcf_tfilter_dump_policy is introduced in commit f8ab1807a9c9 ("net: sched: introduce terse dump flag") while still ignoring the fact that TCA_CHAIN needs a check. This patch does that by complementing the policy to allow the access discussed here can be safe as other cases just choose rtm_tca_policy as the parsing policy.

2024-01-02net: ethtool: Fix symmetric-xor RSS RX flow hash checkGerhard Engleder
Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash") adds a check to the ethtool set_rxnfc operation, which checks the RX flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced with the same commit. It calls the ethtool get_rxfh operation to get the RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is returned. There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which support the ethtool operation set_rxnfc but not get_rxfh. This results in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all these drivers. Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX flow hash.

2024-01-02net/ps3_gelic_net: Add gelic_descr structuresGeoff Levand
In an effort to make the PS3 gelic driver easier to maintain, create two new structures, struct gelic_hw_regs and struct gelic_chain_link, and replace the corresponding members of struct gelic_descr with the new structures. The new struct gelic_hw_regs holds the register variables used by the gelic hardware device. The new struct gelic_chain_link holds variables used to manage the driver's linked list of gelic descr structures. Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: David S.

2024-01-02Merge branch 'bnxt_en-ntuple-fuilter-support'David S. Miller
Michael Chan says: ==================== bnxt_en: Add basic ntuple filter support The current driver only supports ntuple filters added by aRFS. This patch series adds basic support for user defined TCP/UDP ntuple filters added by the user using ethtool. Many of the patches are refactoring patches to make the existing code more general to support both aRFS and user defined filters. aRFS filters always have the Toeplitz hash value from the NIC. A Toepliz hash function is added in patch 5 to get the same hash value for user defined filters. The hash is used to store all ntuple filters in the table and all filters must be hashed identically using the same function and key. v2: Fix compile error in patch #4 when CONFIG_BNXT_SRIOV is disabled. ==================== Signed-off-by: David S.

2024-01-02bnxt_en: Add support for ntuple filters added from ethtool.Michael Chan
Add support for adding user defined ntuple TCP/UDP filters. These filters are similar to aRFS filters except that they don't get aged. Source IP, destination IP, source port, or destination port can be unspecifed as wildcard. At least one of these tuples must be specifed. If a tuple is specified, the full mask must be specified. All ntuple related ethtool functions are now no longer compiled only for CONFIG_RFS_ACCEL.

2024-01-02bnxt_en: Add ntuple matching flags to the bnxt_ntuple_filter structure.Michael Chan
aRFS filters match all 5 tuples. User defined ntuple filters may specify some of the tuples as wildcards. To support that, we add the ntuple_flags to the bnxt_ntuple_filter struct to specify which tuple fields are to be matched. The matching tuple fields will then be passed to the firmware in bnxt_hwrm_cfa_ntuple_filter_alloc() to create the proper filter.

Refactor the logic into a new function bnxt_del_ntp_filters(). The same call will be used when the user deletes an ntuple filter. The bnxt_hwrm_cfa_ntuple_filter_free() function to call fw to free the ntuple filter is exported so that the ethtool logic can call it.
