The current read from network is working from up to down - we have some protocol needing the data from the network, so we build the buffer space for that protocol, add the extra space for headers and pass this buffer down to be filled by nif get call in hope, we have guessed the incoming packet size right. Amazingly enough this approach mostly does work, but not always... So, this update does work from down to up - we allocate buffer (based on MTU or frame size info), fill it up, and pass on for upper layers. The obvious problem is that when we should free the buffer - if at all. In the current implementation the upper layer will free the packet on error or when the packet is no longer needed. While working on the issue, the additional issue did pop up - the bios implementation does not have generic get/put interface but is using pxe udpsend/udpreceive instead. So the udp calls are gone and undi interface is implemented instead. Which in turn means slight other changes as we do not need to have duplicated pxe implementation and can just use dev_net. To align packet content, the actual read from nic is using shifted buffer by ETHER_ALIGN (2). Reviewed by: bapt Differential Revision: https://reviews.freebsd.org/D10232
