Well, I have changed the last sentences of the FAQ entry:
If your 'ssh' version supports the 'ControlPersist' option, you
could customize the variable 'tramp-ssh-controlmaster-options' to
use your 'ControlPath', for example:
(setq tramp-ssh-controlmaster-options
(concat
"-o ControlPath=/tmp/ssh-ControlPath-%%r@%%h:%%p "
"-o ControlMaster=auto -o ControlPersist=yes"))
Note, that "%r", "%h" and "%p" must be encoded as "%%r", "%%h" and
"%%p", respectively. The entries of 'ControlPath', 'ControlMaster'
and 'ControlPersist' can be removed from this setting, if they are
configured properly in your '~/.ssh/config':
(setq tramp-ssh-controlmaster-options "")
