Hi Chengwen, I liked your suggestion and tried making changes, but encountered parsing issue for CFG files with line greater than CFG_VALUE_LEN=256(current value set).
There is a discussion on the similar lines in another patch set: https://patchwork.dpdk.org/project/dpdk/patch/[email protected]/. I believe this patch can be taken as-is and we can come up with the solution when we can increase the CFG_VALUE_LEN as changing CFG_VALUE_LEN in this release is causing ABI breakage.
