[lwip-users] Possible alignment bug in 1.4.0?

[Krzysztof Wesołowski]

I have encountered some HardFaults in rcurrent 1.4.0 version, file
etharp.c code, line 416.

code (stripped from asserts):
static err_t
etharp_send_ip(struct netif *netif, struct pbuf *p, struct eth_addr
*src, struct eth_addr *dst)
{
  struct eth_hdr *ethhdr = (struct eth_hdr *)p->payload;
  ETHADDR32_COPY(&ethhdr->dest, dst);
  ETHADDR16_COPY(&ethhdr->src, src);

  ethhdr->type = PP_HTONS(ETHTYPE_IP);
  return netif->linkoutput(netif, p);
}

Assumes that &ethhdr->dest is 32bit aligned, which is true only for
ETH_PAD_SIZE==0.

Am I doing something wrong?
