---help---
|
|
Packet buffer size. This size includes the TCP/UDP payload plus the
|
|
size of TCP/UDP header, the IP header, and the Ethernet header.
|
|
This value is normally referred to as the MTU (Maximum Transmission
|
|
Unit); the payload is the MSS (Maximum Segment Size).
|
|
|
|
NOTE that this option depends on fragmentation support. By
|
|
supporting fragmentation, we can handle quite large "logical" packet
|
|
sizes. Without fragmentation support, the MTU is equal to the frame
|
|
size and that has already been selected.
