Hi Reshma,
A few comments and questions about your design...
1) How do you envision the reorder library to be used? Based on the
description, it seems like the expectation is that packet order would be
maintained at either the interface/port level or maybe at the RX queue
level. Is that right or

OK, so, in my application packets are RX'ed to a predictable RX queue and core
using RSS.
Then you put them into a predic

Hi All,
I am planning to implement packet reorder library. Details are as below,
please go through them and provide the comments.
Requirement:
To reorder out of ordered packets that are received from
different cores.
Usage:
To be used along with distributor library. Next versio
