  "message": "net: stmmac: propagate FPE preemption-class mapping errors\n\nstmmac_fpe_map_preemption_class() dispatches through the\nstmmac_do_void_callback() helper, which forces the callback\u0027s return\nvalue to 0 whenever the op pointer is populated. As a result the\n-EINVAL returned by dwmac5_fpe_map_preemption_class() (e.g. when a\npreemptible TC owns more than one TXQ under SP scheduling) is silently\nswallowed by every caller.\n\nSwitch the dispatch macro to stmmac_do_callback() so the callback\u0027s real\nresult is propagated, and honour it in the taprio and mqprio qdisc\noffload.\n\nNote that the taprio \"if (ret)\" check in tc_taprio_configure() used to\nbe dead code and now becomes live: a preemptible TC spanning more than\none TXQ under SP scheduling cannot be programmed in hardware, so a\ntaprio or mqprio configuration that previously returned success while\nleaving the preemption-class register unprogrammed now fails with\n-EINVAL. For taprio, the failure also runs the disable path, tearing\ndown the schedule that was just installed; this is the intended\nbehaviour.\n\nFixes: 195e4f409a40 (\"net: stmmac: support fp parameter of tc-mqprio\")\nSigned-off-by: Lorenzo Bianconi \u003clorenzo.bianconi@oss.qualcomm.com\u003e\nLink: https://patch.msgid.link/20260911-stmmac-tc_setup_dwmac510_mqprio-error-path-v3-1-a76b1e2547c1@oss.qualcomm.com\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
