| H A D | if_rlreg.h | diff 117388 Thu Jul 10 18:38:48 MDT 2003 wpaul Add support for the 8139C+ chipset. Unlike the other chips in the 8139 series, the 8139C+ has a descriptor-based DMA mechanism, and its performance is actually pretty respectable. Note: the 8139D chip does not support C+ mode. Only the 8139C+ and 8169 gigE chips support C+ mode. Supported features: - RX and TX checksum offload - hardware VLAN tag insertion/extraction - TX interrupt moderation using the 8139's on-board timer Everything should be properly busdma'ed and endian-independent, so things should work ok on non-x86 platforms. Unfortunately, my call for testers on this code was met with deafening silence, and I don't have access to any non-x86 FreeBSD boxes at the moment, so this is speculation. The device detection code has been cleaned up a little as well (thanks to Michal Mertl) for the patches. There are also updates to the rl(4) man page (which I accidentally checked in before when I updated the dc(4) man page. Oops.) Todo: finish support for the 8169 gigabit ethernet chip. This mainly requires writing an rlgphy driver to handle the 8169's built-in PHY. This will have to wait until I actually get my hands on an 8169 card for testing though. (I still can't find a source for one in the U.S. Suggestions/pointers welcome.) |
