# HG changeset patch # Parent 7be52c02870a053b3a12e75423226c252e256c6b Move the interrupt handler init/cleanup out of e1000.blt This is not device dependant and can be done from the Ethernet subsystem right now, (plus the interrupt handler itself was already in the Ethernet subsytem). diff --git a/rathaxes/samples/e1000/e1000.blt b/rathaxes/samples/e1000/e1000.blt --- a/rathaxes/samples/e1000/e1000.blt +++ b/rathaxes/samples/e1000/e1000.blt @@ -247,7 +247,6 @@ { int bars;
