Description
This PR will replace the earlier #177, of which the branch got lost.
The only significant change is in the function
xNetworkInterfaceOutput(), in which the frame-type is checked before checking the protocol type.I the current driver, outgoing ARP frames get a size warning. It doesn't cause incorrect behaviour, except for the size warnings in the logging.
Test Steps
Define
ipconfigDRIVER_INCLUDED_TX_IP_CHECKSUMas1and send an outgoing ping. The ARP before the PING may not trigger a size warning, and the ICMP checksum shall be calculated correctly.Related Issue
