From: Thomas Monjalon Date: Thu, 29 Oct 2020 07:17:35 +0000 (+0100) Subject: net/pcap: switch Rx timestamp to dynamic mbuf field X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d23d73d088c1;p=dpdk.git net/pcap: 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.
