[dpdk-dev] [PATCH 06/14] net/sfc/base: add function to create packed stream RxQ
Andrew Rybchenko

Sun Dec 24 11:46:36 CET 2017
Encoding packed stream buffer size in RxQ type is not a future-proof
idea taking into account a new RxQ types with extra parameters.
To be consistent make packet stream buffer size a separate parameter.
In order to avoid blowing of the default RxQ create function prototype
add a dedicated function to create packed stream RxQ without not
applicable paramters.
