From: Motomu Utsumi <mot...@hongo.wide.ad.jp>
in add flexfiler it always write to same register address,
so when try to adapt some filters only last one is enabled.
I substitute value based on based on flex_filter->index for reg_off.
in del flexfilter, it delete target filter and
also delete first filter because of similar reason.
I substitute value based on based on it->index for reg_off.
