The interfaces are cc(4), so this is adapter accounting. The numbers you see are coming from hardware MAC statistics that track "on-the-wire" frames. If you want to know if TSO is occurring look for the driver stats for the number of TSO work requests it has sent to the chip: # sysctl dev.cc. | grep tso_wrs Regards, Navdeep > > cc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > > options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> > ether 00:07:43:04:b3:20 > nd6 options=9<PERFORMNUD,IFDISABLED> > media: Ethernet 40Gbase-SR4 <full-duplex> > status: active > cc1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > > options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> > ether 00:07:43:04:b3:20 > nd6 options=9<PERFORMNUD,IFDISABLED> > media: Ethernet 40Gbase-SR4 <full-duplex> > status: active > lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > > options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> > ether 00:07:43:04:b3:20 > nd6 options=9<PERFORMNUD,IFDISABLED> > media: Ethernet autoselect > status: active > groups: lagg > laggproto lacp lagghash l2,l3,l4 > laggport: cc0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> > laggport: cc1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
