commit 52f6042c889c8bb8a3743614ab1aab6f002ba8ba from
git@git.assembla.com:cavium/WindRiver.linux.git
Ratelimit prints from AF error interrupt handlers such as NIX AF
error interrupt, NIX AF RVU error interrupt and NPA AF RVU error
interrupt handler. This prevents unnecessary flooding of error
messages on the console when any AF error interrupt condition
triggers continuously.

commit e4804915b954374aeaa1ab524d3c9b40bd66d5e6 from
git@git.assembla.com:cavium/WindRiver.linux.git
Explicitly disable backpressure in CQ and Aura contexts
during lf teardown to deassert backpressure on link as
clearing CQ.ena or AURA.ena is not sufficient.
Also enable pause frame config everytime lf is allocated to
override previous configurations.

commit 22ed4821a7cf30c580aa14040ab14c685633bba1 from
git@git.assembla.com:cavium/WindRiver.linux.git
When clearing NPA_AQ_RES_S result structure for submitting
a new instruction software needs to wait until hardware
is done with previous instruction. Otherwise software
may clear previous instruction result before
interpreting it.

commit 2e95351b0f314c123ec0e8f28e899bb8a2d293ce from
git@git.assembla.com:cavium/WindRiver.linux.git
A config option is added to disable caching of dynamic entries
like SQEs and stack pages. Also locks down all HW contexts in NDC,
preventing them from being evicted.
This option is useful in reducing number of cache misses thus
getting rid of a probability of hitting couple of related HW issues.
Note: This config option will result in performance loss

commit ee1e75915f4ff00e125adf98c9684c57cae4a88f upstream
Each of the NIX/NPA LFs can choose which ways of their respective
NDC caches should be used to cache their contexts. This enables
flexible configurations like disabling caching for a LF, limiting
it's context to a certain set of ways etc etc. Separate way_mask
for NIX-TX and NIX-RX is not supported.

commit ae73da4ca2c6f6b13665bd353d86b2aea6c95478 from
git@git.assembla.com:cavium/WindRiver.linux.git
To aid in debugging NPA related issues, added support to dump
NPA (pool allocator) block LF's aura and pool hardware contexts in
debugfs. User can check which contexts are enabled currently and dump
it's current HW context.
Three new files 'qsize', 'aura_ctx', 'pool_ctx' are added to the
debugfs at 'sys/kernel/debug/octeontx2/npa/'
"qsize" dumps the current enabled Aura/Pools and corresponding
bitmaps.
Usage:
echo <npalf> > qsize'
cat qsize
To dump the aura_ctx and pool_ctx
'echo <npalf> [{aura/pool} number/all] > {aura/poll}_ctx'
'cat {aura/pool}_ctx'

Upon receiving FLR IRQ for a RVU PF, teardown or cleanup
resources held by that PF_FUNC. This patch cleans up,
NIX LF
- Stop ingress/egress traffic
- Disable NPC MCAM entries being used.
- Free Tx scheduler queues
- Disable RQ/SQ/CQ HW contexts
NPA LF
- Disable Pool/Aura HW contexts
In future teardown of SSO/SSOW/TIM/CPT will be added.
Also added a mailbox message for a RVU PF to request
AF, to perform FLR for a RVU VF under it.

This patch adds support for a RVU PF/VF to disable all Aura/Pool
contexts of a NPA LF via mbox. This will be used by PF/VF drivers
upon teardown or while freeing up HW resources.
A HW context which is not INIT'ed cannot be modified and a
RVU PF/VF driver may or may not INIT all the Aura/Pool contexts.
So a bitmap is introduced to keep track of enabled NPA Aura/Pool
contexts, so that only enabled hw contexts are disabled upon LF
teardown.

Add support for a RVU PF/VF to submit instructions to NPA AQ
via mbox. Instructions can be to init/write/read Aura/Pool/Qint
contexts. In case of read, context will be returned as part of
response to the mbox msg received.

Upon receiving NPA_LF_ALLOC mbox message allocate memory for

to HW. Enable caching of contexts into NPA NDC.
Return pool related info like stack size, num pointers per

Initialize NPA admin queue (AQ) i.e alloc memory for
AQ instructions and for the results. All NPA LFs will submit
instructions to AQ to init/write/read Aura/Pool contexts
and in case of read, get context from result memory.
Added some common APIs for allocating memory for a queue
and get IOVA in return, these APIs will be used by
NIX AQ and for other purposes.
