From a282babcfd922f27e59b7ce7d046a310123a8220 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Fri, 17 Oct 2014 03:14:46 +0000 Subject: [PATCH] i40e: avoid disable of interrupt when changing ITR The call to irq_dynamic_disable was turning off the interrupt completely when trying to set ITR to 0 (for lowest moderation). Just remove the call as setting the values to 0 later in this function will suffice.
