Revision 811c9a4b618ffc7de097490f8dc61b43b8464b9c authored by Lennert Buytenhek on 29 October 2006, 13:15:10 UTC, committed by Russell King on 29 October 2006, 16:52:17 UTC
The second ethernet port on the Thecus n2100 was incorrectly assigned to XINT1 instead of the correct XINT3 (PCI INTB instead of INTD), which caused that port to be non-functional. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
