+Description: Interface is used to configure and connect device channels
+ to component drivers.
+
+ Attributes are visible only when configfs is mounted. To mount
+ configfs in /sys/kernel/config directory use:

+ The attributes:
+
+ buffer_size configure the buffer size for this channel
+
+ subbuffer_size configure the sub-buffer size for this channel
+ (needed for synchronous and isochrnous data)
+
+
+ num_buffers configure number of buffers used for this
+ channel
+
+ datatype configure type of data that will travel over
+ this channel
+
+ direction configure whether this link will be an input
+ or output
+
+ dbr_size configure DBR data buffer size (this is used
+ for MediaLB communiction only)
+
+ packets_per_xact
+ configure the number of packets that will be
+ collected from the network before being
+ transmitted via USB (this is used for USB
+ communiction only)
+
+ device name of the device the link is to be attached to
+
+ channel name of the channel the link is to be attached to
+
+ comp_params pass parameters needed by some components
+
+ create_link write '1' to this attribute to trigger the
+ creation of the link. In case of speculative
+ configuration, the creation is post-poned until
+ a physical device is being attached to the bus.
+
+ destroy_link write '1' to this attribute to destroy an
+ active link
