[PATCH AUTOSEL 4.20 036/105] mlxsw: spectrum: Add VXLAN dependency for spectrum

[Sasha Levin]

From: Ido Schimmel <ido...@mellanox.com>

[ Upstream commit 143a8e038ac599ca73c6354c8af6a8fdeee9fa7d ]

When VXLAN is a loadable module, MLXSW_SPECTRUM must not be built-in:

drivers/net/ethernet/mellanox/mlxsw/spectrum_switchdev.c:2547: undefined
reference to `vxlan_fdb_find_uc'

Add Kconfig dependency to enforce usable configurations.

Fixes: 1231e04f5bba ("mlxsw: spectrum_switchdev: Add support for VxLAN 
encapsulation")
