r8152: Support partial reads for jumbo frame ethernet packets
The RealTek R8153 dongle will only send individual USB packets up to a certain maximum packet size (not quite clear what this is, possibly 2KB). Usually this seems to be enough for our TFTP needs, but depending on TFTP server configuration and network path MTU they may occasionally get bigger. This patch makes sure the driver will not choke if it receives a 9KB jumbo frame in small pieces.
