Also, more netlink commands are introduced to retrieve information from the active channel or configure the active channel with provided options.

According to NCSI spec, the destination MAC field should be 0xFF's, but the source MAC field could be arbitrary one since channel field in NCSI header indicates the source of the packet. There are 3 types of packets depending on the type field in the NCSI packet header: command, response, Asynchronous Event Notification (AEN). The command packets are sent from NCSI enabled interace to the NCSI package or channel for purpose of information retrival or configuration. The response packets, as responses to the received command packets, originate from NCSI package or channel and terminate at NCSI enabled interface. AEN packets are sent from NCSI channel for asynchronous events that might indicate failure detected on the active channel. This implements the functions to handle NCSI packets.

Each package includes multiple channels, up to 32 channels. At one moment, one channel is enabled to provide service to the NCSI enabled interface. Besides, each channel comprises capabilities, modes, filters, version and statistics etc. All of them are resources to NCSI protocol stack. At the meanwhile, the NCSI device seen from NIC driver is represented by "struct ncsi_dev", which is expected to populated and started by NIC driver before the NIC can work. All possible NCSI packages and NCSI channels connected to the NCSI interface are tracked from the NCSI device. Also, the NCSI device recognizes active channel that is currently providing service to NCSI enabled interface. Also, the NCSI requests (pairs of command and response) are embedded in NCSI device. This introduces the data structs to represents the NCSI resources mentioned as above. Also, functions used by NCSI stack internally are implemented. Besides, this introduces kernel config option CONFIG_NET_NCSI to enable NCSI stack.

The most significant one is the disablement of newly introduced topology API. Its ABI couldn't be stabilized enough, so we decided to delay for 4.3 in the end.

In order to allow this to be done without having to support the initial ABI add Kconfig to disable the build and also add some #error statements to the UAPI header so users can't use them. 2015-08-18T16:33:21+00:00 Mark Brown broonie@kernel.org 2015-08-18T05:59:25+00:00 urn:sha1:8c90503bf246bebb48caa5590d41df755ba08550 Since the topology API is still in sufficient flux for changes to be identified disable the use of the userspace ABI by adding #error statements to the code, ensuring that nobody relies on the headers as currently defined. It is expected that this change will be reverted for v4.3.

It's a new API that was introduced in 4.2, and we'd like to avoid ABI change after the release, so it's taken now. As there is no real in-tree user for this API, it should be fairly safe.
