            Bug ID: 13136
           Summary: Long static routes (longer than 255 bytes) are parsed
                    incorrectly by udhcpc
           Product: Busybox
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Networking
          Assignee: unassigned at busybox.net
          Reporter: martin.lewis.x84 at gmail.com
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

udhcpc supports the 'static-routes' option, which depends on long option
support, because static routes may be longer than a single option.

According to RFC 3396, long options are split between multiple options with the
same code. The current version of udhcpc allows duplicate option codes, but
handles them incorrectly by parsing just the last occurrence of the option
(instead of concatenating).

See https://lists.isc.org/pipermail/dhcp-users/2009-July/009879.html for a
configuration example.
