The problem is the (__be32 *) casts. This is a normal pointer to a 32-bit, which is assumed to be aligned, and the cast overrides the packed attribute from the struct. Dereferencing these cast expressions must be done with the macros from asm/unaligned.hAgain, not going to happen.There are only two options for fixing this: 1. Ensure the struct is always aligned. 2. Declare it packed (and fix casts). Refusing to do either leaves us with a broken kernel. Is that what you want?
Once again, please bring this up with davem and also CC netdev at vger.kernel.org as he's the point of contention here. Nicolas
