Hello, I'm hoping someone can help point me in the right direction with an issue I'm having with a Silicom NIC. I'm trying to use this NIC which has a dual 10G interface to generate Netflow records for up to 20 Gbps of network traffic. The problem I'm having is that the interfaces don't appear to come up unless I have connected both interfaces and then from the switch counters it appears it is in some kind of optical bypass mode. Since the card is Intel based, I've been using ixgbe and ixgbe_zc drivers with no luck. Does this card require a specific driver to do what I'm asking of it?
Here is some information on the environment: >From lspci: 07:00.0 Ethernet controller: Intel Corporation 82598EB 10-Gigabit AF Dual Port Network Connection (rev 01) Subsystem: Silicom Ltd.
