| Subject: net: mvneta: fix mtu change on port without link |
| |
| From: Yelena Krivosheev <yelena@marvell.com> |
| |
| [ Upstream commit 8466baf788ec3e18836bd9c91ba0b1a07af25878 ] |
| |
| It is incorrect to enable TX/RX queues (call by mvneta_port_up()) for |
| port without link. Indeed MTU change for interface without link causes TX |
| queues to stuck. |
| |
| Fixes: c5aff18204da ("net: mvneta: driver for Marvell Armada 370/XP |
| network unit") |
