From 06ee266de6ead5b0a5a65d305674a214eac53b94 Mon Sep 17 00:00:00 2001 From: Xiaolong Ye Date: Mon, 13 Jan 2020 10:39:22 +0800 Subject: [PATCH] net/i40e/base: improve AQ log granularity This patch makes it possible to log only AQ descriptors, without the entire AQ message buffers being dumped too. It should greatly reduce kernel log size in cases where a full AQ dump is not needed. Selection is made by setting flags in hw->debug_mask. Additionally, some debug messages that preceded an AQ dump have been moved to I40E_DEBUG_AQ_COMMAND class, which seems more appropriate.
