Author: yongari Date: Thu Jun 18 06:03:58 2009 New Revision: 194426 URL: http://svn.freebsd.org/changeset/base/194426 Log: MFC 193880,193887: r193880: Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc. r193887: fix directory name.
