From 16756d3e77ad58cd07e36cbed724aa13ae5a0278 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 13 Apr 2021 20:46:14 -0700 Subject: ethtool: pause: make sure we init driver stats The intention was for pause statistics to not be reported when driver does not have the relevant callback (only report an empty netlink nest). What happens currently we report all 0s instead. Make sure statistics are initialized to "not set" (which is -1) so the dumping code skips them.
