Subject: [PATCH] common/idpf: remove unnecessary field in vport
Date: Thu, 20 Apr 2023 12:20:38 -0400	[thread overview]
Message-ID: <20230420162038.637079-1-qi.z.zhang@intel.com> (raw)

Remove the pointer to rte_eth_dev instance, as
1. there is already a pointer to  rte_eth_dev_data.
2. a pointer to rte_eth_dev will break multi-process usage.
