Subject: [PATCH] common/idpf: refine get packet type
Date: Fri, 22 Dec 2023 16:51:28 +0000 [thread overview]
Message-ID: <20231222165128.2899806-1-beilei.xing@intel.com> (raw)
From: Beilei Xing <beilei.xing@intel.com>
Since the response of virtual channel virtchnl2_get_ptype_info is
changed on IMC side, driver needs to be updated when requiring
the virtual channel.
