From: Anatoly Burakov Date: Fri, 19 Jun 2020 10:53:49 +0000 (+0100) Subject: examples/l3fwd-power: disable interrupts by default X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=f06493ad733cc20f6b6109453b1443a9a0ffb4c1 examples/l3fwd-power: disable interrupts by default Currently, interrupts are enabled in telemetry and empty poll modes, but they are not used. Switch to disabling interrupts by default, and only enable interrupts for modes that require them.
