    b43: Increase number of RX DMA slots · ccae0e50
    Larry Finger authored
    Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G
    were due to overflow of the RX DMA ring buffer, which was created with 64
    slots. That finding reminded me that I was seeing similar crashed on a netbook,
    which also has a relatively slow processor. After increasing the number of
    slots to 128, runs on the netbook that previously failed now worked; however,
    I found that 109 slots had been used in one test. For that reason, the number
    of slots is being increased to 256.
