Hi Michael,

quoted

+			pr_warn("TimeSync IC pkt recv failed (Err: %d)\n",
+				ret);

Let's use pr_warn_once().

If there's a packet at the head of the ring buffer that specifies a bogus length,
we could take the error path.  But the bad packet stays at the head of the ring buffer,
so if we end up back here again, we'll spit out the same error message.  We
actually should not end up here again because Hyper-V shouldn't interrupt
when adding a packet to a non-empty ring buffer, but who knows what might
happen.

Valid point, will fix this in the next iteration.

Thanks,
Vineeth
