controller. L1 has several threshold/timer registers and they seem to require careful tuned parameters to get best performance. Datasheet for L1 is not available to open source driver writers so age(4) focus on stability and correctness of basic Tx/Rx operation. ATM the performance of age(4) is far from optimal which in turn means there are mis-programmed registers or incorrectly configured registers. Currently age(4) supports all known hardware assistance including - MSI support. - TCP Segmentation Offload. - Hardware VLAN tag insertion/stripping. - TCP/UDP checksum offload. - Interrupt moderation. - Hardware statistics counter support. - Jumbo frame support. - WOL support. L1 gigabit ethernet controller is mainly found on ASUS motherboards. Note, it seems that there are other variants of hardware as known as L2(Fast ethernet) and newer gigabit ethernet (AR81xx) from Atheros. These are not supported by age(4) and requires a seperate driver. Big thanks to all people who reported feedback or tested patches.
