Alternatively looking for if_baudrate might give you some > clues. apart from the typo ("know know") yes the email contained three serious questions, two of which (third party drivers and shops which carry the card) i cannot answer looking at the tree. On top of this, some in-tree drivers may be stale, broken, redundant (say ixgb vs ixgbe), and so on. And not all hardware can do line rate -- not even at 1G, let alone 10G, so it would be good to know also some first hand information on performance. The goal of the question was also to get -- and have on the archives, for the future -- informed feedback ("i have card X and works/does not work with driver Y and performance is Z", see Vlad's reply). > > I think the short answer is - we support almost all even though few are not > (yet) in the tree. wow, that's a lot of information :) seriously though: i have Intel and know it works reasonably well and have published detailed data on that on the netmap page. Vlad has replied about Myricom. I know that Chelsio has a card and supports it. But I have no first-hand information about the others: for instance, do we support Marvell ? which driver ? What about broadcom ? Any other makers&drivers for 10G on FreeBSD ? Hope the question is more clear now. cheers luigi
