[dpdk-dev] could nvm_checksum_validate Error may cause non-functioning of DPDK.

Hi,

    I am trying to work on DPDK-1.5.0r0 with intel i350 dual port NIC
with intel i3 processor on Fedora 18 (kernel-3.11.4). But after
building dpdk when i try to run testpmd application its not working
with some error as...

"EAL: Ask a virtual area of 0x2097152 bytes
EAL: Virtual area found at 0x7faddaa00000 (size = 0x200000)

that CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file
"
When i searched for kernel logs, it shows me as NVM_CHECKSUM_INVALID
for this NIC. As per my knowledge its a EEPROM error in NIC card. So
to work around it i changed the driver code given in dpdk-1.5.0r0 in
dpdk-1.5.0r1/lib/librte_eal/linuxapp/kni/ethtool/igb/e1000_nvm.c to
just return the success messages whenever anyone ask for
nvm_checksum_validate.

But still its not working & showing the above logs. Please help.
Thanx.

The drivers in KNI are only used for ethtool operations with kernel.
The PMD file you are looking for is lib/librte_pmd_e1000/e1000/e1000_nvm.c
