From e684fa34c3a28b4893d43629a02a765a2a71e63e Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Tue, 11 Nov 2014 03:15:03 +0000 Subject: i40e: only warn once of PTP nonsupport in 100Mbit speed Only warn once that PTP is not supported when linked at 100Mbit. Yes, using a static this way means that this once-only message is not port specific, but once only for the life of the driver, regardless of the number of ports. That should be plenty.
