Date: Mon, 14 Sep 2020 17:11:57 -0700 From: Jakub Kicinski <kuba@...nel.org> To: davem@...emloft.net Cc: mkubecek@...e.cz, michael.chan@...adcom.com, saeedm@...dia.com, tariqt@...dia.com, andrew@...n.ch, alexander.duyck@...il.com, netdev@...r.kernel.org, Jakub Kicinski <kuba@...nel.org>, Alexander Duyck <alexander.h.duyck@...ux.intel.com> Subject: [PATCH net-next v3 6/8] ixgbe: add pause frame stats Report standard pause frame stats. They are already aggregated in struct ixgbe_hw_stats. The combination of the registers is suggested as equivalent to PAUSEMACCtrlFramesTransmitted / PAUSEMACCtrlFramesReceived by the Intel 82576EB datasheet, I could not find any information in the HW actually supported by ixgbe.
