This struct should also be __attribute__((__packed__)), right?

Is EtherCard support something else than 8 bits controllers? If yes then we need this attribute

I don't think so, but even if that's not the case, there's no harm in adding it for future proof :)

I am aiming to add support for a wider range of devices, including the 32-bit ones, such as the Arduino M0.
The biggest blocker is the SPI interface - I have a half-complete branch using the Arduino SPI library - see #335.

* keep MAC/IP relations into an ARP 'store'. * fix issue when IP packet is received from local network: answer is no more broadcasted * define ETHERCARD_ARP_STORE_SIZE to set cache size
* less error prone * decrease code size to flash * introduce ethernet_header(), ethernet_payload(), ip_header(), ip_payload().... basic functions to retrieve headers and payloads * use ntoh and hton instead of manual multibytes adaptations. getBigEndianLong has been replaced by standard function ntohl.

[IP] use IP header instead of array offsets
Description
less error prone
decrease code size to flash (save some bytes, see below)
introduce ethernet_header(), ethernet_payload(), ip_header(),
ip_payload().... basic functions to retrieve headers and payloads
use ntoh and hton instead of manual multibytes adaptations.
getBigEndianLong has been replaced by standard function ntohl.
Code size evolution depending on examples
Negative value: save size
Positive value: increase size
