cnic : Cleanup CONFIG_IPV6 & VLAN check

anish · davem330 · commit c99d667e8527 · 2014-09-05T20:47:14.000-07:00
The cnic module needs to ensure that if ipv6 support is compiled as a module,
then the cnic module cannot be compiled as built-in as it depends on ipv6.
Made this check cleaner via Kconfig

Use simpler IS_ENABLED for CONFIG_VLAN_8021Q check
