 239  * general format ("smb:" only; we do not look for "cifs:").

 249  *                  The method of locating the list of workgroups varies
 250  *                  depending upon the setting of the context variable
 251  *                  context->options.browse_max_lmb_count.  This value

 254  *                  a complete list of workgroups is obtained, all master
 255  *                  browsers must be queried, but if there are many
 256  *                  workgroups, the time spent querying can begin to add up.
 257  *                  For small networks (not many workgroups), it is suggested
 258  *                  that this variable be set to 0, indicating query all local
 259  *                  master browsers.  When the network has many workgroups, a

 262  * smb://name/      if name<1D> or name<1B> exists, list servers in

 264  *                  for server ...
