  Changed paths:
    M lib/dpif-netlink-rtnl.c

  Log Message:
  dpif-netlink-rtnl: Retry smaller MTU when default MAX_MTU is too large.

When MAX_MTU is larger than hw supported max MTU,
dpif_netlink_rtnl_create will fail. This leads to
testing failure '11: datapath - ping over gre tunnel'
in 'make check-kmod'.

This patch fixes this issue by retrying a smaller MTU
when MAX_MTU is too large.
