RE: PROBLEM: Bnx2x Checksum/Length Error Over GRE Tunnel

quoted

Tried this on latest net-next [using iproute2] and I didn't manage to
hit the issue you've indicated.
I.e., traffic seemed to work fine on gre tunnels using both mtu sizes
and regardless of whether Tx-checksum-offload was enabled or disabled.

Interesting. Could it be a firmware issue?

All latest drivers use the same FW;  The difference is usually in management
FW, which should have no relevance to a feature such as this.

Care to share a dump [ethtool -d] and lspci [-vvv] outputs for the device?

Thanks,
Yuval
