[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.
