NAME
     device_get_sysctl_ctx, device_get_sysctl_tree — manipulate the sysctl oid tree for driver specific sysctl
     nodes


SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     struct sysctl_ctx_list *
     device_get_sysctl_ctx(device_t dev);

     struct sysctl_oid *
     device_get_sysctl_tree(device_t dev);


DESCRIPTION
     The newbus system automatically adds a sysctl node for each device in the system.  This node can be
     accessed with the device_get_sysctl_tree() function.  The context for the node can be obtained with the
     device_get_sysctl_ctx() function.
