All three patches target net. The L3/L4 filter match count statistics patch (originally patch 4/4) has been split out and will be sent separately against net-next per Andrew Lunn's review of v1. Patch 1 fixes a register corruption bug in the L4 filter port configuration. The XGMAC_L4_ADDR register holds both source and destination port match values in a single register. The original code overwrites the entire register when setting either field, silently erasing the other. This is fixed by using a read-modify-write sequence. Patch 2 fixes the basic flow match parser to properly reject unsupported offload requests with -EOPNOTSUPP instead of silently accepting them. Unsupported cases include partial protocol masks, non-IPv4 network proto, and non-TCP/UDP transport proto. Extack messages are now included so users know exactly which part of the match is unsupported. The -EOPNOTSUPP is also now returned directly instead of using break, which was silently discarding the error on FLOW_CLS_REPLACE operations. Patch 3 fixes a stale action bug on filter deletion. When a filter entry with a drop action is deleted, the action field was not reset, causing it to persist and potentially affect subsequent filter configurations. All three patches fix the original L3/L4 filter implementation introduced in 425eabddaf0f ("net: stmmac: Implement L3/L4 Filters using TC Flower"). ==================== Link: https://patch.msgid.link/20260714023716.29865-1-muhammad.nazim.amirul.nazle.asmade@altera.com Signed-off-by: Paolo Abeni --- c2de9edf4f7027d669fd7a95964353e2c0c46bbd
