From 58aa94f922c1b44e0919d1814d2eab5b9e8bf945 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Thu, 16 Jan 2020 16:14:46 +0100 Subject: devmap: Adjust tracepoint for map-less queue flush MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that we don't have a reference to a devmap when flushing the device bulk queue, let's change the the devmap_xmit tracepoint to remote the map_id and map_index fields entirely. Rearrange the fields so 'drops' and 'sent' stay in the same position in the tracepoint struct, to make it possible for the xdp_monitor utility to read both the old and the new format.
