Updates smoltcp to 0.14.0

Release notes

Sourced from smoltcp's releases.

[0.13.1] - 2026-05-01

• tcp: Fix panic when a listening socket receives a SYN from the unspecified addr.
• tcp: fix SACK sequence number overflow, which could cause a panic when compiling with overflow checks enabled.
• ipv4: Check IPv4 IHL to be at least 20 bytes.

[0.13.0] - 2026-03-20

Highlights of this release are IPv6 SLAAC support, TCP improvements (zero window probes, retransmit fixes, RFC compliance), raw socket enhancements, and a bump to Rust Edition 2024.

• Minimum Supported Rust Version (MSRV) bumped to 1.91.
• Rust Edition bumped to 2024. (#1084)
• heapless dependency bumped to v0.9. (#1083)
• iface
  • IPv6 SLAAC (Stateless Address Autoconfiguration), gated behind a new slaac feature flag. (#1039)
  • Add slaac_updated_at method to check when SLAAC addresses were last updated. (#1130)
  • Add getters for the default IPv4/IPv6 route and is_ipv4_gateway/is_ipv6_gateway helpers. (#1129)
  • Exhaust egress socket state on poll, so sockets don't have to wait for the next poll to send queued data. (#1059)
  • Remove always-Ok Results in consume(). (#1093)
  • Honor any_ip when checking local address. (#1119)
  • Add iface_max_route_count-0 feature flag to disable the routing table entirely. (#1057)
  • Improve IPv4 source address selection for multi-subnet interfaces. (#1074)
  • Fix poll_at returning stale timestamps due to silent_until expiry check. (#1127)
  • Fix fragment payload sizes not being a multiple of eight octets. (#1116)
  • Fix incorrect packet length after defragmentation. (#1094)
  • Fix compilation of IPv6+Multicast without Ethernet. (#1043)
  • Log and drop IPv6 packets requiring fragmentation (IPv6 routers must not fragment). (#1038)
• tcp
  • Add zero window probe support. (#1026)
  • Close socket if the local IP is no longer assigned to the interface. (#1113)
  • Reject bytes outside the receive window. (#1079)
  • Don't accept RST packets on listening sockets. (#1058)
  • Don't send TCP RST when packet is handled by a raw socket. (#1069)
  • Send challenge ACK for duplicate ACK in LAST-ACK state. (#1126)
