The branch main has been updated by whu: URL: https://cgit.FreeBSD.org/src/commit/?id=805dbff6c36a6cd84491aa53a02315fa025734cc commit 805dbff6c36a6cd84491aa53a02315fa025734cc Author: Wei Hu <whu@FreeBSD.org> AuthorDate: 2021-03-15 10:20:52 +0000 Commit: Wei Hu <whu@FreeBSD.org> CommitDate: 2021-03-15 10:33:29 +0000 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.
