Dear Klaus Flittner,

an odd number of preamble nibbles are dropped. Some switches seem to send all packets with such an preamble.
According to the functional specifications of the marvell 88F6180, 6190, 6192 and 6281 the reception of such packets can be enabled by setting bit 22 in register PSC1.

Do you thing setting this by default will not disturb functionality on other hardware? If so, how about encapsulating it in #ifdef with SYS_CONFIG_xx ?
