Subject: [net-next 03/15] ice: Preserve VLAN Rx stripping settings

From: Tony Nguyen <anthony.l.nguyen@...el.com>

When Tx insertion is set, we are not accounting for the state of Rx
stripping.  This causes Rx stripping to be enabled any time Tx
insertion is changed, even when it's supposed to be disabled.
