From 4105de6732f771ea64113851a2ee7172c34d3a7a Mon Sep 17 00:00:00 2001 From: aliguori Date: Wed, 6 Aug 2008 14:11:44 +0000 Subject: only check RCTL_EN in e1000_can_receive() e1000_receive() has code to raise a receive overflow interrupt when the receive buffer head and tail match. However, with the present implementation of e1000_can_receive(), this code is unreachable -- and etherboot breaks as a result.
