usertools: add --status-dev option to devbind
Script displays status for all device types and output is much longer than it used to be. This makes harder to read script output. This patch adds new --status-dev argument to the script to select a device group to display status. Supported device groups: net crypto event mempool Sample usage: ./usertools/ --status-dev mempool Signed-off-by: Ferruh Yigit <>
