Hi Xiao,

Thank you! I add release note and remove the DEV_RX_OFFLOAD_RSS_HASH modification(It may be a mistake). 
I submit the new patch again:) 

Best regards,
Xiaojun

Hi,

This is a feature-add patch, so you need to add release note in doc/guides/rel_notes/release_20_05.rst, that can be included as part of this 5/5 patch.

Another issue, why delete DEV_RX_OFFLOAD_RSS_HASH unconditionally? I think it would impact the existing usage.
