From 3b8428b84539c78fdc8006c17ebd25afd4722d51 Mon Sep 17 00:00:00 2001 From: Joe Damato jdamato@fastly.com Date: Wed, 8 Dec 2021 17:56:33 -0800 Subject: [PATCH] i40e: fix unsigned stat widths
Change i40e_update_vsi_stats and struct i40e_vsi to use u64 fields to match the width of the stats counters in struct i40e_rx_queue_stats.
Update debugfs code to use the correct format specifier for u64.
