From 2b58eec23eae7a457e14938a223e76ba509c2229 Mon Sep 17 00:00:00 2001 From: Mohsin Bashir Date: Mon, 25 Aug 2025 13:02:02 -0700 Subject: [PATCH] eth: fbnic: Reset hw stats upon PCI error [ Upstream commit b1161b1863c5f3d592adba5accd6e5c79741720f ] Upon experiencing a PCI error, fbnic reset the device to recover from the failure. Reset the hardware stats as part of the device reset to ensure accurate stats reporting. Note that the reset is not really resetting the aggregate value to 0, which may result in a spike for a system collecting deltas in stats. Rather, the reset re-latches the current value as previous, in case HW got reset.
