From 89c8023fd46167a41246a56b31d1b3c9a20b6970 Mon Sep 17 00:00:00 2001 From: Liwei Song Date: Wed, 25 Mar 2020 11:50:13 +0800 Subject: nfsroot: set tcp as the default transport protocol UDP is disabled by default in commit b24ee6c64ca7 ("NFS: allow deprecation of NFS UDP protocol"), but the default mount options is still udp, change it to tcp to avoid the "Unsupported transport protocol udp" error if no protocol is specified when mount nfs.
