There are actually two different things by the link you posted, socket buffer size and winpcap buffer size. If your question is about WinpkFilter driver internal buffers then for Windows Vista and later driver preallocates 1000 buffers for 1514 bytes sized packets. This value is hardcoded (changing requires driver recompile) and can’t be changed from user mode application.
