This tool is to demonstrate the use of netlink sockets to read RAS error
counters, which is being proposed via series
"[RFC v2 0/5] Proposal to use netlink for RAS and Telemetry across drm subsystem".

The tool supports the following commands:
READ_ONE, READ_ALL, WAIT_ON_EVENT, LIST_ERRORS

read single error counter:

$ ./drm_ras READ_ONE --device=drm:/dev/dri/card1 --error_id=0x0000000000000005
counter value 0

read all error counters:

$ ./drm_ras READ_ALL --device=drm:/dev/dri/card1
