From: Neerav Parikh Date: Fri, 10 Jul 2015 23:36:02 +0000 (-0400) Subject: i40e/i40evf: Add capability to gather VEB per TC stats X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fe860afb4638f5e62e7d861bfc35a1580fb633bb;p=linux-beck.git i40e/i40evf: Add capability to gather VEB per TC stats This patch adds capability to update per VEB per TC statistics and dump it via ethtool. It also adds a structure to hold VEB per TC statistics. The fields can be filled by reading the GLVEBTC_* counters.
