====================
mlxsw: Small routing improvements

Patch #1 switches the driver to use a unique and stable ECMP/LAG seed.
This allows for consistent behavior across reboots and avoids hash
polarization at the same time.

Patch #2 relaxes the FIB rule validation in the driver to allow the
installation of rules that direct locally generated traffic (iif=lo).
This does not result in a discrepancy between both data paths because
packets received by the device would never match such rules.
