From f11999987bc0b5559ab56dedc6f4ca32fab5438a Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Thu, 19 Nov 2015 11:34:23 -0800 Subject: [PATCH] i40e: clean whole mac filter list Clean the whole mac filter list when resetting after an intermediate add or delete push to the firmware. The code had evolved from using a list from the stack to a heap allocation, but the memset() didn't follow the change correctly. This now cleans the whole list rather that just part of the first element.
