In pcnet32.c where the driver writer sets up her receive buffers there
is this line
lp->rx_dma_addr[i] = pci_map_single(lp->pci_dev, rx_skbuff->tail,
rx_skbuff->len, PCI_DMA_FROMDEVICE);
the length value turns out to be 0 and crashes the running process,ifconfig.
Is making a map for a buffer of length 0 valid at all? If not what the
hell is going on here.
I feel this should say PKT_BUF_SZ instead of rx_skbuff->len which is the
length of skbuff which has been
allocated at this point in the code, this is line 986 in todays checkout.
Something is wrong in any case, any pointers?
