I'm testing Intel 82599EB network adapter. Sometimes link is lost. 1. /usr/src/sys/dev/ixgbe/README said When 82599-based SFP+ devices are connected back to back, they should be set to the same Speed setting via Ethtool. Results may vary if you mix speed settings. But manual speed settings for ixgbe don't work under FreeBSD: # ifconfig -m ix0 ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO> capabilities=1507bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,NETMAP> ... skipped ... media: Ethernet autoselect (10Gbase-SR <full-duplex>) status: active supported media: media autoselect media 10Gbase-SR # ifconfig ix0 media 10Gbase-SR ifconfig: SIOCSIFMEDIA (media): Invalid argument And as I can see it is limited in driver: http://bxr.su/FreeBSD/sys/dev/ixgbe/ixgbe.c#1697 README file is outdated? 2. Link sometimes (but no always) lost aster starting /usr/src/tools/tools/netmap/pkt-gen Sometime link restorted after aboring pkt-gen, sometimes only after power off/on (ifconfig down/up don't help). Is this netmap related issue?
