lpc_eth: add missing ndo_change_mtu()
lpc_eth does a copy of transmitted skbs to DMA area, without checking
skb lengths, so can trigger buffer overflows :
memcpy(pldat->tx_buff_v + txidx * ENET_MAXF_SIZE, skb->data, len);
One way to get bigger skbs is to allow MTU changes above the 1500 limit.
Calling eth_change_mtu() in ndo_change_mtu() makes sure this cannot
happen.
