NIX exposes NIX_AF_SMQ(0..511)_CFG to configure minimum length
of the packet which is being used for zero padding if packet is
less than configured value.
Setting it to default minimum length i.e. 60 bytes.

Due to an errata red algo needs to be set to discard instead of stall
for 96XX C0 silicon for two rate shaping. This workaround is being
already handled for newly created hierarchy but not for dynamic
shaper update cases. This patch hence applies the workaround
even when for shaper dynamic update.

Add dynamic parent and shaper update callbacks that
can be used to change RR Quantum or PIR/CIR rate dynamically
post hierarchy commit. Dynamic parent update callback only
supports updating RR quantum of a given child with respect to
its parent. There is no support yet to change priority or parent
itself.

Modify resource allocation and freeing logic to support

This patch also modifies SQ flush to timeout based on minimum shaper
rate configured. SQ flush is further split to pre/post

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.

Upon ethdev configure, a default hierarchy is
