Madhuri Kumari d115373ff5 Add a note for specifying octal value of permission
In commit[1], we allowed to specify permission to be applied to
TFTP directories using ``[pxe]/dir_permission``. This configuration
is an integer value. This patch adds a note stating that this value
should be an octal number.
