[dpdk-dev] [PATCH v4 4/5] dpaa: enable dpaax library

Shreyansh Jain shreyansh.jain at nxp.com
Mon Oct 15 08:42:01 CEST 2018


With this patch, dpaa bus and ethernet devices on this bus
would start using the physical-virtual library interfaces.

This patch impacts mempool/dpaa, event/dpaa and net/dpaa as
they are dependent on the bus/dpaa and thus impact linkage of
libraries.
