From 2fbdbfaa0c4407547060f8a0ca4d0d04bbf09f9e Mon Sep 17 00:00:00 2001 From: Wei Hu Date: Mon, 15 Mar 2021 10:20:52 +0000 Subject: Hyper-V: hn: Initialize the internal field of per packet info on tx path The RSC support feature introduced a bit field "rm_internal" in struct rndis_pktinfo with total size unchanged. The guest does not use this field in the tx path. However we need to initialize it to zero in case older hosts which are not aware of this field.
