From d639836ab3363f935a9a4336cb4ea3828d0437dd Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Thu, 14 May 2020 12:57:17 +0300 Subject: net: qed: adding hw_err states and handling Here we introduce qed device error tracking flags and error types. qed_hw_err_notify is an entrace point to report errors. It'll notify higher level drivers (qede/qedr/etc) to handle and recover the error. List of posible errors comes from hardware interfaces, but could be extended in future.
