Packet Types—Ethernet Controller I210
859
In this case the packet is split after (82+D+S+N+B) bytes.
N = (IP HDR length – 5) * 4.
A.1.4 Type 2: Ethernet, IPv6
A.1.4.1 Type 2.1: Ethernet (VLAN/SNAP), IPv6, Data
This packet type contains both Ethernet and IPv6 headers while the packet should be a fragmented
packet. If the packet is not fragmented and the next header is not one of the supported types from
Section A.1.3.4 then the header is not split. The header of this type of packet is split/replicated only if
PSRTYPE.PSR_TYPE7 is set.
In this case the packet is split after (54+D+S+N) bytes.
