Using the same test with tcpperf running on one console and a flood
ping on a second, the system lasted 7 minutes before meta->skb was
NULL. The data are:
b43: meta data: skb (null)
dmaaddr 000000004fa820bc
is_last_fragment 1
b43: ring data: nr_slots 256
used_slots 205
current_slot 105
index 1
tx 1
max_used_slots 256
Notice that the DMA queue is not even close to full - there are about
50 slots left or enough space for 25 more packets.
This error was generated with the DMA queue full patch applied.
