247 * smb:// Show all workgroups.
248 *
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
252 * determine the maximum number of local master browsers to
253 * query for the list of workgroups. In order to ensure that
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
260 * reasonable setting for this variable might be around 3.

263 * workgroup, else, if name<20> exists, list all shares
