Subject: [PATCH] boot.src: Provide dsa_core.blacklist bootarg when booting via
NFS
This setup is a bit special as Linux kernel (4.19) is not supporting
in-kernel NFS rootfs mount and Distributed Switch Architecture (DSA)
operation.
For that reason it was necessary to provide a bootarg to allow userspace
enable it afterwards if needed.
