From dd151d7200ae6c5cfddbec7eb1a55ba8319e12b2 Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Wed, 6 Dec 2017 17:31:59 +0300 Subject: NTB: ntb_test: Add ntb_tool port tests Multi-port interface is now available in ntb_tool driver. According to the new NTB API, there might be more than two devices connected over NTB. It means each device can have multiple freely enumerated ports. Each port got index assigned by NTB hardware driver. This test is performed to determine the local and peer ports as well as their indexes.
