Hi, This series enables some ethtool and tc-flower filters to be offloaded to igb-based network controllers. This is useful when the system configurator want to steer kinds of traffic to a specific hardware queue.
The first two commits are bug fixes. The basis of this series is to export the internal API used to configure address filters, so they can be used by ethtool, and extending the functionality so an source address can be handled. Then, we enable the tc-flower offloading implementation to re-use the same infrastructure as ethtool, and storing them in the per-adapter "nfc" (Network Filter Config?) list. But for consistency, for destructive access they are separated, i.e. an filter added by tc-flower can only be removed by tc-flower, but ethtool can read them all. Only support for VLAN Prio, Source and Destination MAC Address, and Ethertype are supported for now. Open question: - igb is initialized with the number of traffic classes as 1, if we want to use multiple traffic classes we need to increase this value, the only way I could find is to use mqprio (for example). Should igb be initialized with, say, the number of queues as its "num_tc"?
