Hi Bryan, thank you so much for reviewing, I really appreciate it.

It appears you moved this packet_length assignment from just below the following if block, however  you left out the le32_to_cpu.See next comment
Correct on both counts. This is a merge snafu that crept in when I
rebased to Alexey's very recent little/big endian patch, at the last
minute.
My tests didn't catch it, because I'm running on a little-endian cpu,
where le32_to_cpu() compiles to a nop.

Had I had the good sense to run sparse on every patch, like Jakub has,
I would have caught it...
