[net PATCH 0/9] Fixes for CN10K and CN9xxx platforms

[Subbaraya Sundeep]

Hi,

This patchset has consolidated fixes in Octeontx2 driver
handling CN10K and CN9xxx platforms. When testing the
new CN10K hardware some issues resurfaced like accessing
wrong register for CN10K and enabling loopback on not supported
interfaces. Some fixes are needed for CN9xxx platforms as well.

Below is the description of patches

Patch 1: AF sets RX RSS action for all the VFs when a VF is
brought up. But when a PF sets RX action for its VF like Drop/Direct
to a queue in ntuple filter it is not retained because of AF fixup.
This patch skips modifying VF RX RSS action if PF has already
set its action.

Patch 2: When configuring backpressure wrong register is being read for
LBKs hence fixed it.

Patch 3: Some RVU blocks may take longer time to reset but are guaranteed
to complete the reset. Hence wait till reset is complete.

Patch 4: For enabling LMAC CN10K needs another register compared
to CN9xxx platforms. Hence changed it.

Patch 5: Adds missing barrier before submitting memory pointer
to the aura hardware.

Patch 6: Increase polling time while link credit restore and also
return proper error code when timeout occurs.

Patch 7: Internal loopback not supported on LPCS interfaces like
SGMII/QSGMII so do not enable it.

Patch 8: When there is a error in message processing, AF sets the error
response and replies back to requestor. PF forwards a invalid message to
VF back if AF reply has error in it. This way VF lacks the actual error set
by AF for its message. This is changed such that PF simply forwards the
actual reply and let VF handle the error.

Patch 9: ntuple filter with "flow-type ether proto 0x8842 vlan 0x92e"
was not working since ethertype 0x8842 is NGIO protocol. Hardware
parser explicitly parses such NGIO packets and sets the packet as
NGIO and do not set it as tagged packet. Fix this by changing parser
such that it sets the packet as both NGIO and tagged by using
separate layer types.

Thanks,
Sundeep

[net PATCH 1/9] octeontx2-af: Do not fixup all VF action entries

[Subbaraya Sundeep]

AF modifies all the rules destined for VF to use
the action same as default RSS action. This fixup
was needed because AF only installs default rules with
RSS action. But the action in rules installed by a PF
for its VFs should not be changed by this fixup.
This is because action can be drop or direct to
queue as specified by user(ntuple filters).
This patch fixes that problem.

[net PATCH 2/9] octeontx2-af: Fix LBK backpressure id count

In rvu_nix_get_bpid() lbk_bpid_cnt is being read from
wrong register. Due to this backpressure enable is failing
for LBK VF32 onwards. This patch fixes that.

[net PATCH 5/9] octeontx2-pf: cn10k: Ensure valid pointers are freed to aura

[Subbaraya Sundeep]

From: Geetha sowjanya <gakula@marvell.com>

While freeing SQB pointers to aura, driver first memcpy to
target address and then triggers lmtst operation to free pointer
to the aura. We need to ensure(by adding dmb barrier)that memcpy
is finished before pointers are freed to the aura. This patch also
adds the missing sq context structure entry in debugfs.

It's been observed that sometimes link credit restore takes
a lot of time than the current timeout. This patch increases
the default timeout value and return the proper error value
on failure.

[net PATCH 8/9] octeontx2-pf: Forward error codes to VF

[Subbaraya Sundeep]

PF forwards its VF messages to AF and corresponding
replies from AF to VF. AF sets proper error code in the
replies after processing message requests. Currently PF
checks the error codes in replies and sends invalid
message to VF. This way VF lacks the information of
error code set by AF for its messages. This patch
changes that such that PF simply forwards AF replies
so that VF can handle error codes.

This appears to be merged to netdev/net as commit 03c82e80ec28 ("Merge

have had a hiccup.
