Subject: [PATCH] mbuf: delete dynamic fields copy in hdr copy
Date: Tue, 14 Dec 2021 15:56:05 +0800	[thread overview]
Message-ID: <20211214075606.979-1-gaoxiangliu0@163.com> (raw)

Because dynamic fields are registered by the DPDK application,
so it is up to the application to decide whether to copy the value of
dynamic fields.
So delete dynamic fields copy in __rte_pktmbuf_copy_hdr.
It's more flexible for the DPDK application,
and is useful for improving performance.

Fixes: 4958ca3a443a ("mbuf: support dynamic fields and flags")
