busybox: allow libiproute to handle table ids larger than 255
These changes are required for compatibility with ConnMan, which by default uses table ids greater than 255. Signed-off-by: Lukasz Nowak <lnowak@tycoint.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

+Subject: [PATCH v2] libiproute: handle table ids larger than 255
+
+Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
+In order to preserve compatibility, the old 8-bit field: rtm_table is still
+in use when table id is lower than 256.
+
+Add support for the 32-bit table id (RTA_TABLE attribute) in:
+- ip route print
+- ip route modify
+- ip rule print
+- ip rule modify
+
+Add printing of table ids to ip route.
+
+Changes are compatible with the mainline iproute2 utilities.
+
+These changes are required for compatibility with ConnMan, which by default
+uses table ids greater than 255.
+
+Upstream-Status: Submitted [http://lists.busybox.net/pipermail/busybox/2016-December/084989.html]
