Detailed Description

IPv6 version of ICMP, as per RFC 4443.

Definition in file icmp6.h.

Function Documentation

Send an icmpv6 'destination unreachable' packet.

Parameters:

p	the input packet for which the 'unreachable' should be sent, p->payload pointing to the IPv6 header
c	ICMPv6 code for the unreachable type

Definition at line 217 of file lwip_icmp6.c.

Process an input ICMPv6 message.

Called by ip6_input.

Will generate a reply for echo requests. Other messages are forwarded to nd6_input, or mld6_input.

Parameters:

p	the mld packet, p->payload pointing to the icmpv6 header
inp	the netif on which this packet was received

Definition at line 81 of file lwip_icmp6.c.

Send an icmpv6 'packet too big' packet.

Parameters:

p	the input packet for which the 'packet too big' should be sent, p->payload pointing to the IPv6 header
mtu	the maximum mtu that we can accept

Definition at line 230 of file lwip_icmp6.c.

Send an icmpv6 'parameter problem' packet.

Parameters:

p	the input packet for which the 'param problem' should be sent, p->payload pointing to the IP header
c	ICMPv6 code for the param problem type
pointer	the pointer to the byte where the parameter is found

Definition at line 257 of file lwip_icmp6.c.

Send an icmpv6 'time exceeded' packet.

Parameters:

p	the input packet for which the 'unreachable' should be sent, p->payload pointing to the IPv6 header
c	ICMPv6 code for the time exceeded type
