Increase the size of a call's Rx window from 32 to 63 - ie. one less than the size of the ring buffer. This makes large data transfers perform better when the Tx window on the other side is around 64 (as is the case with Auristor's YFS fileserver). If the server window size is ~32 or smaller, this should make no difference.
