Subject: [PATCH 11/12] net: mvneta: fix mtu change on port without link
Git-commit: 8466baf788ec3e18836bd9c91ba0b1a07af25878
Patch-mainline: v4.19-rc1
References: git-fixes
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.

network unit")
