[BRIDGE]: Unaligned accesses in the ethernet bridge
I see lots of kernel unaligned access to 0xa0000001009dbb6f, ip=0xa000000100811591 kernel unaligned access to 0xa0000001009dbb6b, ip=0xa0000001008115c1 kernel unaligned access to 0xa0000001009dbb6d, ip=0xa0000001008115f1 messages in my logs on IA64 when using the ethernet bridge with 2.6.16. Appended is a patch to fix them. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
