Or why are these patches necessary? Correct. You cannot use etf qdisc with "offload" on for OF platforms, including imx93. Doing that will end with "return -EINVAL" in tc_setup_etf(). I am working with imx98mp, but there should not be any difference for imx93. /Esben _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
