MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The introduction of set_bit() and clear_bit() calls in batman-adv
wrongly passed bitmasks and not the bit numbers to these functions.
This leads to broken capability checks.
Fixing this by making the capability enum a non-bitmasked one and by
that passing non-masked values to set_bit()/clear_bit().
