The only way of recovering it is to flap the interface (ifconfig down then up). # Steps to Reproduce 1. Bring up an e1000 interface on a QNX target. 2. Run a continuous ping to the target e1000 interface from a directly connected neighbor. 3. Change the media type "ifconfig em0 media 100baseTX mediaopt full-duplex= ". 4. Sometimes you need to change the media type more than once e.g. "ifconfig em0 media 1000baseT mediaopt full-duplex" # Actual Results Ping stops reaching target. 64 bytes from 10.242.241.213: icmp_seq=3D1 ttl=3D64 time=3D0.707 ms 64 bytes from 10.242.241.213: icmp_seq=3D2 ttl=3D64 time=3D0.721 ms 64 bytes from 10.242.241.213: icmp_seq=3D3 ttl=3D64 time=3D0.649 ms 64 bytes from 10.242.241.213: icmp_seq=3D4 ttl=3D64 time=3D0.768 ms 64 bytes from 10.242.241.213: icmp_seq=3D1 ttl=3D64 time=3D8268 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D3 ttl=3D64 time=3D6219 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D9 ttl=3D64 time=3D76.1 ms 64 bytes from 10.242.241.213: icmp_seq=3D10 ttl=3D64 time=3D0.541 ms 64 bytes from 10.242.241.213: icmp_seq=3D11 ttl=3D64 time=3D0.604 ms 64 bytes from 10.242.241.213: icmp_seq=3D12 ttl=3D64 time=3D0.754 ms 64 bytes from 10.242.241.213: icmp_seq=3D13 ttl=3D64 time=3D1.02 ms 64 bytes from 10.242.241.213: icmp_seq=3D14 ttl=3D64 time=3D0.676 ms 64 bytes from 10.242.241.213: icmp_seq=3D15 ttl=3D64 time=3D0.609 ms 64 bytes from 10.242.241.213: icmp_seq=3D16 ttl=3D64 time=3D0.591 ms 64 bytes from 10.242.241.213: icmp_seq=3D1 ttl=3D64 time=3D20397 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D3 ttl=3D64 time=3D18349 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D10 ttl=3D64 time=3D11204 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D12 ttl=3D64 time=3D9165 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D13 ttl=3D64 time=3D8141 ms (DUP!) 64 bytes from 10.242.241.213: icmp_seq=3D16 ttl=3D64 time=3D5101 ms (DUP!) >From 10.242.241.212 icmp_seq=3D50 Destination Host Unreachable >From 10.242.241.212 icmp_seq=3D51 Destination Host Unreachable >From 10.242.241.212 icmp_seq=3D52 Destination Host Unreachable >From 10.242.241.212 icmp_seq=3D53 Destination Host Unreachable >From 10.242.241.212 icmp_seq=3D54 Destination Host Unreachable # Expected Results Ping continues to reach target (possibly some packets dropped).
