  "message": "net/ethernet/freescale: rework quiesce/activate for ucc_geth\n\n[ Upstream commit 79dde73cf9bcf1dd317a2667f78b758e9fe139ed ]\n\nugeth_quiesce/activate are used to halt the controller when there is a\nlink change that requires to reconfigure the mac.\n\nThe previous implementation called netif_device_detach(). This however\ncauses the initial activation of the netdevice to fail precisely because\nit\u0027s detached. For details, see [1].\n\nA possible workaround was the revert of commit\nnet: linkwatch: add check for netdevice being present to linkwatch_do_dev\nHowever, the check introduced in the above commit is correct and shall be\nkept.\n\nThe netif_device_detach() is thus replaced with\nnetif_tx_stop_all_queues() that prevents any tranmission. This allows to\nperform mac config change required by the link change, without detaching\nthe corresponding netdevice and thus not preventing its initial\nactivation.\n\n[1] https://lists.openwall.net/netdev/2020/01/08/201\n\nSigned-off-by: Valentin Longchamp \u003cvalentin@longchamp.me\u003e\nAcked-by: Matteo Ghidoni \u003cmatteo.ghidoni@ch.abb.com\u003e\nSigned-off-by: David S.
