Subject: [dpdk-dev] [PATCH 1/6] rte_mbuf: copy offload flags when doing attach/clone of mbuf
Date: Fri, 07 Mar 2014 10:13:36 -0800 [thread overview]
Message-ID: <20140307181421.045171437@vyatta.com> (raw)
In-Reply-To: <20140307181335.024904493@vyatta.com>
[-- Attachment #1: mbuf-ol-flags.patch --]
[-- Type: text/plain, Size: 631 bytes --]
rte_pktmbuf_attach copies the packet meta data but does not
copy the offload flags. This means that cloned packets lose
their offload settings such as vlan tag.
