Wei Bo-Er \(Jason\)，您好！
but when i skip the checksum in the
icmp.c, ping the board using ping 192.168.0.3 -l 1001 -t and ping
192.168.0.3 -l 1000 -t , it successed. Why ? a bug?

You may check out your network card and it's driver
to see if it is word(2 bytes) alignment and you have made the wrong
byte as the last byte of the received packet.

why
hi every one
i
have a problem about icmp.c
when i ping my board , useing
ping 192.168.0.3 l -999 -t , it failed its debug info is
"checksum failed for received ICMP echo."
but when i ping
the board using ping 192.168.0.3 l -1000 -t . it
successed
i found that when the size of packet is odd
bytes if fails and when it si parity bytes it
successes.
why ?
thank you
