Re: [dpdk-dev] [PATCH v4 6/6] DPDK changes for accommodating ENIC PMD

David,

I tested it now, and it looks like the length is proper in
dev->men_resource[0].len without this change.
Not sure what changed in my workspace as I clearly remember seeing it
wrong and hence added the extra statement in the lib.

I shall remove it in v5.
Thanks for pointing it out, David.

Regards,
-Sujith

I still think this part is wrong.
The length should have been populated by pci_parse_sysfs_resource().
Are you sure this length is 0 ?

Can you do give me the result of cat
/sys/bus/pci/devices/$your_device_pci_address/resource ?

Thanks.
