From c3d26b75c22b0487c452bd610338aa015eae517b Mon Sep 17 00:00:00 2001 From: Alan Brady Date: Tue, 29 Aug 2017 05:32:32 -0400 Subject: [PATCH] i40e: re-enable PTP L4 capabilities for XL710 if FW >6.0 Starting with XL710 FW 5.3 PTP L4 was disabled for XL710 due to a bug. The bug has since been resolved in XL710 FW >6.0 and PTP L4 can now be re-enabled on those devices with updated firmware.
