220.127.116.11. Inter-Packet Gap Generation and Insertion
If you set Average Inter-packet Gap to 12 in the F-Tile Ethernet Intel® FPGA Hard IP parameter editor, the TX MAC maintains the minimum inter-packet gap (IPG) between transmitted frames required by the IEEE 802.3 Ethernet standard. The standard requires an average minimum IPG of 96 bit times (or 12-byte times). The MAC uses a deficit idle counter to allow the actual gap between frames to vary as needed to meet the maximum throughput requirements of the link.
If you set Average Inter-packet Gap to 10 or 8, the TX MAC maintains a minimum average IPG of 10 or 8 bytes accordingly. This option is provided as an intermediate option to allow you to enforce an IPG that does not conform to the Ethernet standard, but which increases the throughput of your IP core.
