[OpenWrt-Devel] Wireless monitor interface causes device to run out of memory

I noticed that my bcm53xx devices run out of memory after running
wireless monitor interface for about 2 days.

This problem occurs since 0694d08c84fd ("bcm53xx: switch to kernel
4.9") which bumped kernel from 4.4.53 to 4.9.14 and is still present
when using 4.14.

Interestingly this memory drain requires at least one of:
net.ipv6.conf.default.forwarding=1
net.ipv6.conf.all.forwarding=1
to be set. OpenWrt happens to use both by default.

This is *not* a memory leak. Restarting wireless interfaces frees all
consumed memory.

Any idea what may be causing this?
