From 9daf5a7695f70b60c498aac079f908c81ffe4d15 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Mon, 26 Nov 2007 16:17:52 -0600 Subject: [PATCH] phylib: marvell: add support for TX-only and RX-only Internal Delay Previously, Internal Delay specification implied the delay be applied to both TX and RX. This patch allows for separate TX/RX-only internal delay specification.
