This reverts commit 1c5e670d6a5a8e7e99b51f45e79879f7828bd2ec.
LTS 5.15 pulled in several lpfc "SLI Path split" patches. The Path
Split mods were a 14-patch set, which refactors the driver from
to split the sli-3 hw (now eol) from the sli-4 hw and use sli4
structures natively. The patches are highly inter-related.
Given only some of the patches were included, it created a situation
where FLOGI's fail, thus SLI Ports can't start communication.
Reverting this patch as its one of the partial Path Split patches
that was included.

scsi: lpfc: Rework MIB Rx Monitor debug info logic

scsi: lpfc: Rework MIB Rx Monitor debug info logic
[ Upstream commit bd269188ea94e40ab002cad7b0df8f12b8f0de54 ]
The kernel test robot reported the following sparse warning:
arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates
bits from constant value (369 becomes 69)
On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro
usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated
leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not
work properly.
Replace the Rx Table atomic_t indexing logic with a new
lpfc_rx_info_monitor structure that holds a circular ring buffer. For
locking semantics, a spinlock_t is used.

Revert "scsi: lpfc: SLI path split: Refactor lpfc_iocbq"
This reverts commit 1c5e670d6a5a8e7e99b51f45e79879f7828bd2ec.
LTS 5.15 pulled in several lpfc "SLI Path split" patches. The Path
Split mods were a 14-patch set, which refactors the driver from
to split the sli-3 hw (now eol) from the sli-4 hw and use sli4
structures natively. The patches are highly inter-related.
Given only some of the patches were included, it created a situation
where FLOGI's fail, thus SLI Ports can't start communication.
Reverting this patch as its one of the partial Path Split patches
that was included.

scsi: lpfc: Rework MIB Rx Monitor debug info logic
[ Upstream commit bd269188ea94e40ab002cad7b0df8f12b8f0de54 ]
The kernel test robot reported the following sparse warning:
arch/arm64/include/asm/
scsi: lpfc: Rework MIB Rx Monitor debug info logic
[ Upstream commit bd269188ea94e40ab002cad7b0df8f12b8f0de54 ]
The kernel test robot reported the following sparse warning:
arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates
bits from constant value (369 becomes 69)
On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro
usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated
leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not
work properly.
Replace the Rx Table atomic_t indexing logic with a new
lpfc_rx_info_monitor structure that holds a circular ring buffer. For
locking semantics, a spinlock_t is used.
