From 0a4533facb49b0ca0d7520fee09270a82017e8fe Mon Sep 17 00:00:00 2001 From: Long Li Date: Fri, 11 Dec 2020 12:48:21 -0800 Subject: [PATCH] net/netvsc: ignore unsupported packet on sync command On netvsc initialization, the host VSP may send a NVS_TYPE_TXTBL_NOTE packet while executing a VSP command synchronously. Instead of returning an error, ignore this packet as we don't use it for DPDK.
