           Summary: Incorrect processing of DNS info from DHCP
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: networking
        AssignedTo: norume at aps.anl.gov
        ReportedBy: sebastien.bourdeauducq at gmail.com


1) When the /etc/resolv.conf file is built, the code reads the
rtems_bsdnet_ntpserver table instead of the rtems_bsdnet_nameserver
table (line 1092 of rtems_dhcp.c).
2) The variable rtems_bsdnet_nameserver_count is not set to 0 at the
beginning of the DHCP request, which means that when DHCP is restarted,
the DNS entries keep piling up until the table is full (3 entries), at
which point the new DNS will not be taken into account at all.
