From 8a72edd9cb232b868c38373e041b03db1220e779 Mon Sep 17 00:00:00 2001 From: Haiyue Wang Date: Fri, 31 Jul 2020 12:27:13 +0800 Subject: [PATCH] net/ice: fix Tx hang with TSO The variables 'td_offset' and 'td_tag' should be reset to 0 for every burst packet, otherwise the fields of Tx Descriptor will be set wrong, this will cause the MDD event error, and Tx will hang.
