Pyun YongHyeon e0b7b101ce Fix a bug introduced in r199011. When bge(4) reuses loaded RX ... buffers it should also reinitialize RX descriptors otherwise some stale data could be passed to controller. This could end up with mbuf double free or unexpected NULL pointer dereference in upper stack. To fix the issue, save loaded buffer's length and reinitialize RX descriptors with the saved value whenever bge(4) reuses the loaded RX buffers. While I'm here, increase the number of RX buffers to 512 from 256. This simplifies RX buffer handling as well as giving more RX buffers. Controller supports just fixed number of RX buffers (i.e. 512) and bge(4) used to rely on hope that our CPU is fast enough to keep up with the controller. With this change, bge(4) will use 1MB for RX buffers but I don't think it would cause problems in these days. Reported by: marcel Tested by: marcel		2010-06-05 23:29:24 +00:00
