Table A.2.18 defines the functions included in the Ethernet filter library (efilter.c). In the Network Driver Reference, Chapter 2, Section 2.2 defines several filter library macros. A NIC driver can access these functions and macros by including the efilter.h file.
The driver must contain three action functions the Ethernet filter library functions can call back: MacChangeFilter, MacChangeEthAddresses, and MacCloseAction. For more information about these functions, see Section A.2.1. The NIC driver registers these functions in a call to the Ethernet filter library function EthCreateFilter.
