Michael Brown 2d3f2b2446 [ncm] Use large multi-packet buffers by default Some devices have a very small number of internal buffers, and rely on being able to pack multiple packets into each buffer. Using 2048-byte buffers on such devices produces throughput of around 100Mbps. Using a small number of much larger buffers (e.g. 32kB) increases the throughput to around 780Mbps. (The full 1Gbps is not reached because the high RTT induced by the use of multi-packet buffers causes us to saturate our 256kB TCP window.) Since allocation of large buffers is very likely to fail, allocate the buffer set only once when the device is opened and recycle buffers immediately after use. Received data is now always copied to per-packet buffers. If allocation of large buffers fails, fall back to allocating a larger number of smaller buffers. This will give reduced performance, but the device will at least still be functional. Share code between the interrupt and bulk IN endpoint handlers, since the buffer handling is now very similar.
