[PATCH v3 08/15] soc: octeontx2: Add RVU block LF provisioning support

From: sunil . kovvuri
Date: Tue Sep 04 2018 - 12:29:31 EST

From: Sunil Goutham <sgoutham@xxxxxxxxxxx>

Added support for a RVU PF/VF to request AF via mailbox
to attach or detach NPA/NIX/SSO/SSOW/TIM/CPT block LFs.
Also supports partial detachment and modifying current
LF attached count of a certian block type.

Signed-off-by: Sunil Goutham <sgoutham@xxxxxxxxxxx>
