From a1df906c5be75ce2c7633e06c688607ec088ca35 Mon Sep 17 00:00:00 2001 From: Carolyn Wyborny Date: Thu, 28 Feb 2019 09:52:48 -0800 Subject: [PATCH] i40e: change behavior on PF in response to MDD event TX MDD events reported on the PF are the result of the PF misconfiguring a descriptor and not because of "bad actions" by anything else. No need to reset now because if it results in a Tx hang, the Tx hang check will take care of it.
