wengzhe opened a new pull request, #7683:
URL: https://github.com/apache/incubator-nuttx/pull/7683
## Summary
patches included:
- net/icmpv6: Fix `ipv6->len` in icmpv6_reply
- The `ipv6->len` is the length excluding the IPv6 header, so need to be
`dev->d_len - IPv6_HDRLEN`.
- net/icmpv6: Fix `datalen` in icmpv6_reply
- The `datalen` indicates the whole len of original packet, which will
become the payload inside icmpv6 packet.
- net/icmpv6: Fix icmpv6 checksum calculation in icmpv6_reply
- The second param of icmpv6_chksum is `iplen`, which indicates `The size
of the IPv6 header`.
## Impact
- Fix `icmpv6_reply` logic
## Testing
Manually tested when trying to implement TIME_EXCEEDED reply for ttl <= 0
(will be submitted a few days later)
