From 570773c5801cc6c322534d6b1d1551e23664103e Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Sun, 19 Jun 2011 21:51:25 +0000 Subject: [PATCH] emaclite: enable transmit and receive time stamping. This patch enables software (and phy device) time stamping. Since this MAC uses phylib, adding the hooks make hardware time stamping in the phy possible. Compile tested only.
