David Cermak 32ca6039a0 fix(lwip): reject invalid DHCP MTU option values
Validate MTU from DHCP option 26 against RFC 2132 minimum (68 bytes)
before applying to netif->mtu, preventing rogue DHCP servers from
setting MTU to 0 or other dangerously low values that cause integer
wraparound in IPv4 fragmentation.
