Subject: [PATCH 03/10] vdpa/nfp: fix the logic of reconfiguration
Date: Fri, 26 Apr 2024 15:48:24 +0800	[thread overview]
Message-ID: <20240426074831.1729792-4-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20240426074831.1729792-1-chaoyong.he@corigine.com>

From: Xinying Yu <xinying.yu@corigine.com>

The ctrl words of vDPA is locate on the extend word, so should
use the 'nfp_ext_reconfig()' rather than 'nfp_reconfig()'.

Also replace the misuse of 'NFP_NET_CFG_CTRL_SCATTER' macro
with 'NFP_NET_CFG_CTRL_VIRTIO'.

Fixes: b47a0373903f ("vdpa/nfp: add datapath update")
