Subject: [net-next PATCH 00/10] Support for OcteonTx2 98xx silcion

From: Subbaraya Sundeep <sundeep.lkml@...il.com>

OcteonTx2 series of silicons have multiple variants, the
98xx variant has two network interface controllers (NIX blocks)
each of which supports upto 100Gbps. Similarly 98xx supports
two crypto blocks (CPT) to double the crypto performance.
The current RVU drivers support a single NIX and
CPT blocks, this patchset adds support for multiple
blocks of same type to be active at the same time.

Also the number of serdes controllers (CGX) have increased
from three to five on 98xx. Each of the CGX block supports
upto 4 physical interfaces depending on the serdes mode ie
upto 20 physical interfaces. At a time each CGX block can
be mapped to a single NIX. The HW configuration to map CGX
and NIX blocks is done by firmware.

NPC has two new interfaces added NIX1_RX and NIX1_TX
similar to NIX0 interfaces. Also MCAM entries is increased
from 4k to 64k. To support the 64k entries extended set
is added in hardware which are at completely different
register offsets. Fortunately new constant registers
can be read to figure out the extended set is present
or not.

This patch set modifies existing AF and PF drivers
in below order to support 98xx:
- Prepare for supporting multiple blocks of same type.
  Functions which operate with block type to get or set
  resources count are modified to operate with block address
- Manage allocating and freeing LFs from new NIX1 and CPT1 RVU blocks.
- NIX block specific initialization and teardown for NIX1
- Based on the mapping set by Firmware, assign the NIX block
  LFs to a PF/VF.
- Multicast entries context is setup for NIX1 along with NIX0
- NPC changes to support extended set of MCAM entries, counters
  and NIX1 interfaces to NPC.
- All the mailbox changes required for the new blocks in 98xx.
- Since there are more CGX links in 98xx the hardcoded LBK
  link value needed by netdev drivers is not sufficient any
  more. Hence AF consumers need to get the number of all links
  and calculate the LBK link.
- Debugfs changes to display NIX1 contexts similar to NIX0
- Debugfs change to display mapping between CGX, NIX and PF.
