Current driver uses static LMTST region allocated by firmware.
Firmware allocated memory for LMTST is available in PF/VF BAR2.
Using this memory have performance impact as this is mapped as
device memory. There is another option to allocate contiguous
memory at run time and map this in LMT MAP table with the
help of AF driver. With this patch dynamic allocated memory
is used for LMTST.
Also add myself as maintainer for crypto octeontx2 driver

Provide an option in Inline IPsec configure mailbox to configure the
CPT_AF_LFX_CTL:CTX_ILEN for inline CPT LF attached to CPT RVU PF.
This is needed to set the ctx ilen to size of inbound SA for
HW errata IPBUCPT-38756. Not setting this would lead to new context's
not being fetched.
Also set FLR_FLUSH in CPT_LF_CTX_CTL for CPT LF's as workaround
for same errata.

CPT LF must be reset and follow CPT LF disable sequence
suggested by HW team, when driver exits.
This patch adds code for the same.

Scatter Gather input format for CPT has changed on CN10KB/CN10KA B0 HW
to make it compatible with NIX Scatter Gather format to support SG mode
for inline IPsec. This patch modifies the code to make the driver works
for the same. This patch also enables CPT firmware load for these chips.

On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF)
handles resource allocation and configuration for PFs and their VFs.
PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a
mailbox region. The PF then forwards these messages to the AF.
This patch adds code to configure inline-IPsec HW resources for
CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

LDWB is getting incorrectly used in HW when
CPT_AF_LF()_PTR_CTL[IQB_LDWB]=1 and CPT instruction queue has less than
320 free entries. So, increase HW instruction queue size by 320 and give
320 entries less for SW/NIX RX as a SW workaround.

CPT result format had changed for CN10K HW to accommodate more
fields. This patch adds support to use new result format and
new LMTST lines for CPT operations on CN10K platform.

On CN10K platform transmit/receive buffer alloc and free from/to
hardware had changed to support burst operation. Whereas pervious
silicon's only support single buffer free at a time.
To Support the same firmware allocates a DRAM region for each PF/VF for
storing LMTLINES. These LMTLINES are used to send CPT commands to HW.
PF/VF LMTST region is accessed via BAR4. PFs LMTST region is followed
by its VFs mbox memory. The size of region varies from 2KB to 256KB
based on number of LMTLINES configured.
This patch adds support for mapping of PF/VF LMTST region.

CPT RVU Local Functions(LFs) needs to be attached to the
PF/VF to submit the instructions to CPT.
This patch adds the interface to initialize and attach
the LFs. It also adds interface to register the LF's
interrupts.
