This boolean parameter controls whether smbd 8 will support SMB3 multi-channel. This parameter was added with version 4.4. Note that this feature was still considered experimental up to 4.14. Due to dependencies to kernel APIs of Linux or FreeBSD, it's only possible to use this feature on Linux and FreeBSD for now. For testing this restriction can be overwritten by specifying force:server multi channel support=yes in addition. This option is enabled by default starting with to 4.15 (on Linux and FreeBSD). yes
