--- Comment From julian.wiedm...@de.ibm.com 2017-03-07 03:38 EDT--- Frank, please note the second part of the APAR description: 2: When a virtual NIC reflects the characteristics of the NIC via the QUERY_CARD_INFO assist, the port speed and lan type could be improved. Problem conclusion 2: The QUERY_CARD_INFO simulation was updated to reflect a LAN type of Fiber and a speed of 10 Gigabit. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1667828 Title: Network device on z/VM instance incorrectly reports line speed Status in Ubuntu on IBM z Systems: Incomplete Status in linux package in Ubuntu: Incomplete Bug description: Line speed is incorrectly reported on z/VM instances in /sys when compared to what is claimed to be supported and advertised. for example, ethtool shows supported and advertised speeds of 1000Mb/s but /sys is only indicating 10Mb/s. ubuntu@hwe0008:~$ ethtool enc600 Settings for enc600: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 10Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Cannot get wake-on-lan settings: Operation not permitted Link detected: yes ubuntu@hwe0008:~$ cat /sys/class/net/enc600/speed 10 I'm presuming this issue lies somewhere in the qeth driver: P: /devices/qeth/0.0.0600/net/enc600 E: DEVPATH=/devices/qeth/0.0.0600/net/enc600 E: ID_NET_DRIVER=qeth_l2 E: ID_NET_LINK_FILE=/lib/systemd/network/99-default.link E: ID_NET_NAME=enc600 E: ID_NET_NAME_MAC=enx02280b04 E: ID_NET_NAME_PATH=enc600 E: ID_PATH=ccwgroup-0.0.0600 E: ID_PATH_TAG=ccwgroup-0_0_0600 E: IFINDEX=2 E: INTERFACE=enc600 E: SUBSYSTEM=net E: SYSTEMD_ALIAS=/sys/subsystem/net/devices/enc600 /sys/subsystem/net/devices/enc600 E: TAGS=:systemd: E: USEC_INITIALIZED=3784115 This is not an issue on my LPAR that uses the same drivers (but also adds ctcm and zfcp, so maybe therein lies the difference in speed reporting?)
