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.
