Victor Nogueira 526f28bd0f net/sched: act_mirred: Add carrier check ... There are cases where the device is adminstratively UP, but operationally down. For example, we have a physical device (Nvidia ConnectX-6 Dx, 25Gbps) who's cable was pulled out, here is its ip link output: 5: ens2f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether b8:ce:f6:4b:68:35 brd ff:ff:ff:ff:ff:ff altname enp179s0f1np1 As you can see, it's administratively UP but operationally down. In this case, sending a packet to this port caused a nasty kernel hang (so nasty that we were unable to capture it). Aborting a transmit based on operational status (in addition to administrative status) fixes the issue.
