- include/atrf.h (atrf_driver_spec), lib/atrf.c (atrf_driver_spec): new function to retrieve the local or remote/final driver spec - lib/atrf.c (struct atrf_dsc, atrf_open, atrf_close): record the local driver spec - lib/driver.h (struct atrf_driver): new driver function "driver_spec" to retrieve the driver spec - lib/atnet.c (struct atnet_dsc, atnet_open, atnet_close): maintain a cache for the driver spec - lib/atnet.c (atnet_driver_spec, atnet_driver): added support for the "driver_spec" function - atrf-proxy/PROTOCOL, atrf-proxy/atrf-proxy.c (cmd_zero): added command SPEC to retrieve the (final) driver spec - atrf-id/atrf-id.c (usage, main): added option -s to retrieve the driver spec. One -s retrieves the local spec, -s -s the remote/final.
