Module dhcp4
:
  • Support for interfaces other than Ethernet (SLIP, PPP, ...)
Global LWIP_NETIF_TX_SINGLE_PBUF
: TCP and IP-frag do not work with this, yet:
Global SNTP_CHECK_RESPONSE

: discard reply if any of the LI, Stratum, or Transmit Timestamp fields is 0 or the Mode field is not 4 (unicast) or 5 (broadcast).

  • >= 4

: to check that the Root Delay and Root Dispersion fields are each greater than or equal to 0 and less than infinity, where infinity is currently a cozy number like one second. This check avoids using a server whose synchronization source has expired for a very long time.
