Hi Kamalesh,

Please try the following patch:

commit 1de440616ac84679902d045b4476effcebfae400

    net: fix vbus-enet Kconfig dependencies

    We currently select VBUS_PROXY when vbus-enet is enabled, which is
    the wrong direction.  Not all platforms will define VBUS-PROXY, and
    venet depends on its inclusion.  Therefore, lets fix vbus-enet to
    properly depend on the presence of VBUS_PROXY to get this right.
