Subject: [dpdk-stable] [PATCH] net/netvsc: ignore NVS_TYPE_TXTBL_NOTE while executing a sync command
Date: Thu, 10 Dec 2020 23:52:44 -0800 [thread overview]
Message-ID: <1607673164-3683-1-git-send-email-longli@linuxonhyperv.com> (raw)
From: Long Li <longli@microsoft.com>
On netvsc initialization, the host VSP may send a NVS_TYPE_TXTBL_NOTE packet
while executing a VSP command synchronously.
Ignore this packet as we don't use it for DPDK.
