-
-   - Additional ethtool functionality, including link status test and EEPROM

-
-   - Support for Zero copy on 82550-based adapters. This feature provides 
-     faster data throughput and significant CPU usage improvement in systems 
-     that use the relevant system call (sendfile(2)).
-
-   - Support for large MTU-enabling interface (1504 bytes) with kernel's

-   - Support for polling on RX

-   - Support for Wake On LAN* on 82550 and 82559-based adapters
