From 1c1538be1da768fe0209a11e1bdf9dd7ab38905a Mon Sep 17 00:00:00 2001 From: Jeff Kirsher Date: Fri, 20 May 2011 19:48:55 -0700 Subject: pch_gbe: Move the OKI Semiconductor driver Move the OKI Semiconductor driver into driver/net/ethernet/oki-semi/ and make the necessary Kconfig and Makefile changes. Note: there is no documented maintainer for this driver, so I CC'd the last 2 major contributors.
