Hi folks, What's the level of checksum offloading support in the ixgbe driver? With driver version 3.21.2, I seem to be able to enable/disable checksum offloading via ethtool (3.1). I have it enabled ...
$ ethtool -i eth6 driver: ixgbe version: 3.21.2 firmware-version: 0x61bd0001 bus-info: 0000:08:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes $ ethtool -k eth6 Offload parameters for eth6: rx-checksumming: on tx-checksumming: on [...] ... but when I replay a pcap trace whose packets have broken IP and TCP checksums on this machine via tcpreplay, the checksums remain incorrect according to tcpdump on a different, packet-receiving machine. Shouldn't the transmitting driver be fixing them? Or am I barking up the wrong tree here and this is a tcpreplay problem, rather than a driver one? Thanks for any insights, -C. ------------------------------------------------------------------------------ Slashdot TV. Video for Nerds.
