From 1db19db7f5ff4ddd3b1b6dd2092a87298ee5bd0b Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Thu, 7 Jul 2016 18:01:32 +0200 Subject: net: tracepoint napi:napi_poll add work and budget An important information for the napi_poll tracepoint is knowing the work done (packets processed) by the napi_poll() call. Add both the work done and budget, as they are related. Handle trace_napi_poll() param change in dropwatch/drop_monitor and in python perf script netdev-times.py in backward compat way, as python fortunately supports optional parameter handling.
