__lpc_handle_xmit() has two bugs :

1) It can leak skbs in case TXSTATUS_ERROR is set

2) It can wake up txqueue while no slot was freed.

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.

This patch adds device tree support for lpc_eth.c.

The runtime option for MII/RMII is solved via the "phy-mode" property, SRAM
("IRAM") usage for DMA can be chosen via "use-iram".

Probably a leftover from ancient code...

In parallel to the integration of lpc_eth.c, dev_hw_addr_random() has been
renamed to eth_hw_addr_random(). This patch fixes it also in the new driver
lpc_eth.c.
