From 317bfcf67c323a22da9910ccab680ffe82f3235d Mon Sep 17 00:00:00 2001 From: "Daniel P. Carvalho" Date: Thu, 24 Sep 2026 10:33:03 -0300 Subject: [PATCH] arch/arm/stm32h7: declare NETDEV_TX_STAMP capability flag Advertise NETDEV_TX_STAMP in dev.d_features during stm32_ethinitialize() when CONFIG_STM32_ETH_TIMESTAMP_TX is enabled, indicating that the STM32H7 Ethernet driver provides hardware TX timestamping.
