Subject: [PATCH net-next v5 1/4] octeon_ep: add PF-VF mailbox communication
Implement mailbox communication between PF and VFs.
PF-VF mailbox is used for all control commands from VF to PF and
asynchronous notification messages from PF to VF.
Signed-off-by: Shinas Rasheed <srasheed@...vell.com>
---
V5:
- Reordered patch to exclude redundant code refactored in later patch
V4: https://lore.kernel.org/all/20231213035816.2656851-2-srasheed@marvell.com/
- Include [1/4] in the subject for this patch, which was lost in V3
V3: https://lore.kernel.org/all/20231211063355.2630028-2-srasheed@marvell.com/
- Corrected error cleanup logic for PF-VF mbox setup
- Removed double inclusion of types.h header file in octep_pfvf_mbox.c
V2: https://lore.kernel.org/all/20231209081450.2613561-2-srasheed@marvell.com/
- Remove unused variable
V1: https://lore.kernel.org/all/20231208070352.2606192-2-srasheed@marvell.com/
