Hardware: Intel EP server with 2x "Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz"
IB cards: QLogic Corp. IBA7322 QDR InfiniBand HCA (rev 02) , Mellanox
Technologies MT27500 Family [ConnectX-3]
OS: Redhat 6.4, kernel updated to latest RH supplied kernel via KSplice
technology
InfiniBand Software: tried IntelIB-IFS.RHEL6-x86_64.7.2.1.1.22 (based on OFED
1.5.4.1) or OFED-3.5-MIC-alpha1
Problem - offloading checksumming does not work, although the Kernel
documentation indicates it does
[root@eha001 ~]# ethtool -K ib0 tx on
Cannot set device tx-checksumming settings: Operation not supported
IPoIB connected mode is switched of:
SET_IPOIB_CM=no
This problem exists on both Mellanox/Qlogic cards with either SW stack
mentioned. Could anyone advise on this problem?
Thanks
Michael
