From: Thomas Monjalon Date: Thu, 29 Oct 2020 03:02:58 +0000 (+0100) Subject: net/dpaa2: switch Rx timestamp to dynamic mbuf field X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=61c41e2e3993ef1208e5bae0ca7f6c6e4f479283;p=dpdk.git net/dpaa2: switch Rx timestamp to dynamic mbuf field The mbuf timestamp is moved to a dynamic field in order to allow removal of the deprecated static field. The related mbuf flag is also replaced.
