From f8dd0ecbb74d4b220b105d77c0633945ebb5453e Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 24 Jun 2008 22:16:04 +0100 Subject: DM9000: Allow the use of the NSR register to get link status. The DM9000's internal PHY reports a copy of the link status in the NSR register of the chip. Reading the status when polling for link status is faster as it eliminates the need to sleep, but does not print as much information. Add an platform flag to force this behaviour, and a Kconfig option to allow it to be forced to the faster method always.
