another issues was found, see https://dev.openwrt.org/ticket/7552#comment:69

"...under high load and have found that probably some of the silent freezes
are due to overflow of the RX DMA buffer, seems like b43 does not
handlre such a situation at all."

https://dev.openwrt.org/attachment/ticket/7552/840-b43-workaround-rx-fifo-overflow.patch

the patch is working so far, but is only a workaround.
has somebody a better code-idea?
