   2 Date:           June 2015
   3 KernelVersion:  4.3
   4 Description:
   5                 This group contains policies mandating Master/Channel allocation
   6                 for software sources wishing to send trace data over an STM
   7                 device.

   9 What:           /config/stp-policy/<device>.<policy>
  10 Date:           June 2015
  11 KernelVersion:  4.3
  12 Description:
  13                 This group is the root of a policy; its name is a concatenation
  14                 of an stm device name to which this policy applies and an
  15                 arbitrary string. If <device> part doesn't match an existing
  16                 stm device, mkdir will fail with ENODEV; if that device already
  17                 has a policy assigned to it, mkdir will fail with EBUSY.

  19 What:           /config/stp-policy/<device>.<policy>/device
  20 Date:           June 2015
  21 KernelVersion:  4.3
  22 Description:
  23                 STM device to which this policy applies, read only. Same as the
  24                 <device> component of its parent directory.

  27 Date:           June 2015
  28 KernelVersion:  4.3
  29 Description:
  30                 Policy node is a string identifier that software clients will
  31                 use to request a master/channel to be allocated and assigned to
  32                 them.

  34 What:           /config/stp-policy/<device>.<policy>/<node>/masters
  35 Date:           June 2015
  36 KernelVersion:  4.3
  37 Description:
  38                 Range of masters from which to allocate for users of this node.
  39                 Write two numbers: the first master and the last master number.

  41 What:           /config/stp-policy/<device>.<policy>/<node>/channels
  42 Date:           June 2015
  43 KernelVersion:  4.3
  44 Description:
  45                 Range of channels from which to allocate for users of this node.
  46                 Write two numbers: the first channel and the last channel
  47                 number.
