From 38edddb81172e8b8decb057c0cd23271583a5fa0 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Thu, 24 May 2018 16:45:57 +0200 Subject: xdp: add tracepoint for devmap like cpumap have Notice how this allow us get XDP statistic without affecting the XDP performance, as tracepoint is no-longer activated on a per packet basis. V5: Spotted by John Fastabend. Fix 'sent' also counted 'drops' in this patch, a later patch corrected this, but it was a mistake in this intermediate step.
