emac lwIP at91 fix
There are differnet problems in the lwIP / at91/emac combination.
- the at91 driver caculates the needed bufferspace wrong.
- the at91 driver dont remove every broken packet from the emac buffer.
- the at91 driver blocks on some transmit errors.
- the lwIP/eCOS interface has some polling loops which dont give the control to
other threads.
- there is a strange requirement for the PBUF and INPACKET buffer to be bigger
then the MAILBOX-size.
