When rx_buf is allocated we need to account for IPHETH_IP_ALIGN, which reduces the usable size by 2 bytes. Otherwise we have 1512 bytes usable instead of 1514, and if we receive more than 1512 bytes, ipheth_rcvbulk_callback is called with status -EOVERFLOW, after which the driver malfunctiones and all communication stops.
Fixes: ipheth 2-1:4.2: ipheth_rcvbulk_callback: urb status: -75
