[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.
