When my OpenELEC server stopped supporting SMB1 by default I decided to
bite the bullet and abandon mount_smbfs, which does not support
anything higher than SMB1.  (See the STANDARDS section of the
mount_smbfs(8) manual page.)

In my case, I switched to the sysutils/fusefs-smbnetfs port.  It uses
Samba4 under the hood, so supports both SMB2 and SMB3, making it more
compatible with other OSes (like macOS).  I found fusefs-smbnetfs a
little bit of a pain to set up, but very reliable.  Its main advantage,
for me, is supporting modern SMB standards.

Cheers,

Paul.
