[dpdk-stable] [PATCH v3 01/23] bus/fslmc: fix to use ci value for qbman 5.0

[Hemant Agrawal]

From: Youri Querry <youri.querry_1@nxp.com>

Random portal hangs observed on device with QBMAN 5.0

This fixes few random packet hang issues in event mode.
Few things fixed it.
1. Generally, pi == ci, no need for extra checks.
2. The proper initializations in init with ci

Fixes: 1b49352f41be ("bus/fslmc: rename portal pi index to consumer index")

[Hemant Agrawal]

From: Nipun Gupta <nipun.gupta@nxp.com>

Reading of word un-aligned values after reading word aligned
values lead to corrution of memory, such that older value.
This patch make changes such that word alignedaccess is made,

[dpdk-stable] [PATCH v3 03/23] net/dpaa2: fix link get API implementation

[Hemant Agrawal]

From: Rohit Raj <rohit.raj@nxp.com>

According to DPDK Documentation, rte_eth_link_get API can wait up to 9
seconds for auto-negotiation to finish and then returns link status.

In current implementation of rte_eth_link_get API in DPAA2 drivers, it
was not waiting for auto negotiation to finish and was returning link
status DOWN
It can cause issues with DPDK applications which relies on
rte_eth_link_get API for link status and does not support link status
interrupt.
Similar kind of issue was seen in TRex Application.

This patch fixes this bug by adding wait for up to 9 seconds for auto
negotiation to finish.
