35867a370f net/octeontx2: fix PTP configurations for VF
Issue has been observed if PTP is already enabled on PF and
later VFs are configured. Since PTP requires mbuf data off
to be shifted by 8 bytes, due to this l3fwd/l2fwd was not
working with VFs.
Also some extra garbage bytes were observed in packet data
when ptp was enabled.

c261680cdb net/octeontx2: support SDP interface
System DPI Packet Interface Unit (SDP) is a co-processor
of OCTEON TX2 which provides PCIe endpoint support for a
remote host to DMA packets into and out of the OCTEON TX2 SoC.
SDP interface comes in to live only when it is connected in
EP mode. It exposes input and output queue pairs to remote host
for instruction input and packet output. It can be used as
a communication channel between remote host and OCTEON TX2.
Host machine needs to use corresponding user/kernel mode
driver to communicate with SDP interface on OCTEON TX2 SoC.

SDP interface support is limited to SDP PF device now.
No SDP VF support.

195981133a common/octeontx2: fix mbox memory access
Octeontx2 PMD's mailbox client uses device memory to send messages
to mailbox server in the admin function Linux kernel driver.
The device memory used for the mailbox communication needs to
be qualified as volatile memory type to avoid unaligned device
memory accesses because of compiler's memory access coalescing.

This patch modifies the mailbox request and responses as volatile
type which were non-volatile earlier and accessed from unaligned
memory addresses which resulted in bus errors on Fedora 30 with
gcc 9.1.1.

processing a packet can be known:
    <read_clock val at any time> - mbuf->timestamp

Calling mbox for reading raw clock ticks in fastpath is very
expensive so its value is derived from time stamp counter(tsc)

delta (by how much tsc is lagging from raw clock value).

05a58afca1 common/octeontx2: add uplink message support
The events like PHY link status change by AF or PHY configuration
change by PF would call for the uplink message.
The AF initiated uplink would land it in PF and PF would further
forward to VF(if it is intended for that specific VF)

The PF initiated uplink would be distributed to all active VFs.
This patch adds support for the same.

302e7d4958 common/octeontx2: add PF to VF mailbox IRQ and msg handlers
PF has additional responsibility being server for VF messages
and forward to AF and once AF process it then forward
the response back to VF.
otx2_vf_pf_mbox_irq() will process the VF mailbox request and
af_pf_wait_msg() will until getting a response back from AF.
