We've been doing a LOT of 10GB nic testing, and what I can tell you is that it really depends on what you are doing.
Do you need FCoE? Do you need RDMA? Do you need low latency? Do you need high bandwidth and lowest possible latency? Do you need the lowest possible latency, but don't care about as much about bandwidth? Do you care about either? The qlogic and emulex 10gb nics work just fine, but are geared towards things like FCoE, and although they work for everyday use we've had problems with things like multicast. We've had serious problems with the intel neteffect cards as the first generation were prone to heating up and melting, and the second generation caused kernel panics. We are now testing their third generation and have not had any issues *yet* We have had good luck with the Chelsio cards. We have had great lab results with the mellanox cards. We have had good luck with the solarflare cards as well (low latency cards, not really great for high bandwidth, requires preloader for lowest latency... lots of caveats to consider). In every single case we have had to use the most recent drivers for these cards as the ones that come (if they come) with red hat are either buggy or do not preform as well as the newer drivers.
