AH = 0Ch BX = network descriptor or one of the following: FFFCh for kernel ICMP statistics (see #03459) FFFDh for kernel UDP statistics (see #03458) FFFEh for kernel IP statistics (see #03457) FFFFh for kernel TCP statistics (see #03456) DS:DX -> 64-byte buffer
Return:
CF clear if successful buffer filled CF set on error AX = error code (see #03319)
Notes: The fields filled in for a network descriptor depend on the protocol family used by that descriptor's connection. This function is not supported by Beame&Whiteside's BWPCTCP v3.0a shim
