Hi Jouni,

We had this bug after many weeks of using bgscan learn.
Its database only grows, the entries are never removed.
Please consider again this patch:
http://patchwork.ozlabs.org/patch/169799/
or please propose different solution to remove entries.
Otherwise after some time bgscan learn database is full and main 
advantage of bgscan learn - scanning only on particular channels - 
disappears.
