OpenWRT metarouter patch v1.2

Based on http://naberius.de/2015/01/10/openwrt-barrier-breaker-metarouter-instance-on-mikrotik-rb-2011/ - i’ve “fixed” the panic issuing network interfaces in Barrier Breaker.

The main issue with network is the rxbuf size. I did not made other checks, but i saw a packet that’s >= 300bytes leads kernel to crash, what leads to 1600 (Old RXBUF) - 300 == 1300 - for some kind of another stuff. So i increased RXBUF to 10300 and compiled. Its running now a Privoxy and i tested a Ubuntu ISO download from a local mirror and archived my link total speed (5mbps), so for a baby step, is enough. Also in kdoc (link in gist above), skb_put really leads to panic if buffer dont fit the allocation.

I published the patch here: https://gist.github.com/leleobhz/61cd38b851d254a0cee6

I tried your patch but it crashes the router for a while when there is network connected:

Is it because of “skb_put really leads to panic if buffer dont fit the allocation.”? Any idea how to proceed to solve this issue?
