BOOL AirpcapSetKernelBuffer ( PAirpcapHandle  AdapterHandle,
UINT  BufferSize 

Set the size of the kernel packet buffer for this adapter.

AdapterHandle Handle to the adapter.
BufferSize New size, in bytes.
TRUE on success.
Every AirPcap open instance has an associated kernel buffer, whose default size is 1 Mbyte. This function can be used to change the size of this buffer, and can be called at any time. A bigger kernel buffer size decreases the risk of dropping packets during network bursts or when the application is busy, at the cost of higher kernel memory usage.

don't use this function unless you know what you are doing. Due to caching issues and bigger non-paged memory consumption, bigger buffer sizes can decrease the capture performace instead of improving it.
