    Subject[PATCH 4.4 138/230] net: Set rtm_table to RT_TABLE_COMPAT for ipv6 for tables > 255
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Kalash Nainwal <kalash@arista.com>

    [ Upstream commit 97f0082a0592212fc15d4680f5a4d80f79a1687c ]

    Set rtm_table to RT_TABLE_COMPAT for ipv6 for tables > 255 to
    keep legacy software happy. This is similar to what was done for
    ipv4 in commit 709772e6e065 ("net: Fix routing tables with
    id > 255 for legacy software").
