From: Sunil Goutham <sgoutham@xxxxxxxxxxx> This patchset is a continuation to earlier submitted three patch series to add a new driver for Marvell's OcteonTX2 SOC's Resource virtualization unit (RVU) admin function driver. 1. octeontx2-af: Add RVU Admin Function driver https://www.spinics.net/lists/netdev/msg528272.html 2. octeontx2-af: NPA and NIX blocks initialization https://www.spinics.net/lists/netdev/msg529163.html 3. octeontx2-af: NPC parser and NIX blocks initialization https://www.spinics.net/lists/netdev/msg530252.html This patch series adds support for below RVU generic: - Function Level Reset irq handler When FLR is triggered for PFs, AF receives interrupt. This patchset adds logic for cleaning up of NPA, NIX and NPC block resources being used by PF. - Mailbox communication between AF and it's VFs. Unlike VFs of PF1-PFn, AF which is PF0 can communicate with it's VFs directly. Added support for the same. - AF's VFs IO configuration These VFs are mapped to use internal HW loopback channels instead of CGX LMACs. Each pair of VFs work as two of ends of hardwired interfaces. VF0's TX is VF1's Rx & viceversa. NPC block: - MCAM entry management Alloc/Free of contiguous/non-contiguous and lower/higher priority MCAM entry allocation and programming support. - MCAM counters management and map/unmap with MCAM entries - Default KEY extract profile - HW errata workarounds NIX block: - Minimum and maximum allowed packet length config - HW errata workarounds Few more changes like shift to use mutex instead of spinlock etc are done in this patchset. Changes from v2: 1 Fixed commit message of patch 'Relax resource lock into mutex' to a more unambiguous one. - Suggested by David Miller. Changes from v1: 1 Converted all mailbox message handler API names to small letters from mixed small and capital letters. - Suggested by David Miller. 2 Fixed endian issues in patch 'Add support for stripping STAG/CTAG' - Suggested by Arnd Bergmann 3 Elaborated commit message of patch 'Add FLR interrupt handler' to make it a bit more easy to understand. - Suggested by Arnd Bergmann Will fix the padding and alignment in mailbox message structure in a follow-up patch.
