From 548c36e983f346621b5cb9ab031e4383e9996576 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 30 Jan 2008 22:04:05 -0800 Subject: sk98lin: remove obsolete driver All the hardware supported by this driver is now supported by the skge driver. The last remaining issue was support for ancient dual port SysKonnect fiber boards, and the skge driver now does these correctly (p.s. sk98lin was always broken on these old dual port boards anyway).
