6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Suman Ghosh <[email protected]> [ Upstream commit 16809472409d998afcda402e32b8229b389337c4 ] During link down event, we were doing netif_tx_stop_all_queues() first and then netif_carrier_off(). This can cause a potential race since carrier is still on during down event. This patch reverse the calling order to fix the issue.
