09dfbdf4c7 netutls/dhcpc: treat EINTR as normal errno 
A return code of EINTR is perfectly normal, and isn't an error as such.
It's an indication that your program may need to do something because
a signal occurred, but if not, should re-call recv().

83505e217b dhcpc: Rename timeout Kconfig 
NETUTILS_DHCPC_RECV_TIMEOUT -> NETUTILS_DHCPC_RECV_TIMEOUT_MS

Recently its unit has been changed from second to millisecond. [1]
Using the same Kconfig name for a different meaning is a pitfall
for an upgrade. I was using 3ms timeout because of this.

This commit renames it so that at least the default value
is used for a careless user like me.

98dfaa3eff dhcpc abnormal block 
The logic changes are as follows:
1、Loop sending the DISCOVER up to CONFIG_NETUTILS_DHCPC_RETRIES times
   and exit if failure
2、Loop sending the REQUEST up to CONFIG_NETUTILS_DHCPC_RETRIES times
   and exit if failure

- check for minimum packet length (44 bytes, which includes the fields we
  read next)
- pass the correct remaining buffer length to dhcpc_parseoptions()
- dhcpc_parseoptions(): ensure we never read past the end of the buffer

    Using the SOL_IP socket options level isn't portable;
