CONFIG_NET_IPV6_FRAGMENT_MAX_COUNT

How many packets to reassemble at a time

Type: int

Help

How many fragmented IPv6 packets can be waiting reassembly simultaneously. Each fragment count might use up to 1280 bytes of memory so you need to plan this and increase the network buffer count.

Direct dependencies

NET_IPV6_FRAGMENT && NET_IPV6 && !NET_RAW_MODE && NETWORKING

(Includes any dependencies from ifs and menus.)
