This series extends the NCSI driver to configure multiple packages and/or channels simultaneously. Since the RFC series this includes a few extra changes to fix areas in the driver that either made this harder or were roadblocks due to deviations from the NCSI specification.
Patches 1 & 2 fix two issues where the driver made assumptions about the capabilities of the NCSI topology. Patches 3 & 4 change some internal semantics slightly to make multi-mode easier. Patch 5 introduces a cleaner way of reconfiguring the NCSI configuration and keeping track of channel states. Patch 6 implements the main multi-package/multi-channel configuration, configured via the Netlink interface.
Readers who have an interesting NCSI setup - especially multi-package with HWA - please test! I think I've covered all permutations but I don't have infinite hardware to test on.
Changes in v2: - Updated use of the channel lock in ncsi_reset_dev(), making the channel invisible and leaving the monitor check to ncsi_stop_channel_monitor(). - Fixed ncsi_channel_is_tx() to consider the state of channels in other packages.
Samuel Mendoza-Jonas (6): net/ncsi: Don't enable all channels when HWA available net/ncsi: Probe single packages to avoid conflict net/ncsi: Don't deselect package in suspend if active net/ncsi: Don't mark configured channels inactive net/ncsi: Reset channel state in ncsi_start_dev() net/ncsi: Configure multi-package, multi-channel modes with failover
