869
Identification is incremented on each packet.
Flags Field Definition:
The Flags field is defined as follows. Note that hardware does not evaluate or change these bits.
•MF - More Fragments
• NF - No Fragments
• Reserved
The I210 does TCP segmentation, not IP fragmentation. IP fragmentation might occur in transit through
a network's infrastructure.
