[PATCH 1/8] bus/dpaa: fix bus scan for DMA devices

[vanshika.shukla]

From: Gagandeep Singh <g.singh@nxp.com>

if there is no sec devices available, code is not scanning QDMA dev
This patch fix this problem by adding a goto statement instead
of return in case no sec device available.

[PATCH 7/8] net/dpaa: restrict MTU config for shared intf

[vanshika.shukla]

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

Since DPDK was able to configure mtu in VSP/Shared interface  mode,
it was causing misconfiguration of the hw which further caused crashes.

This patch allow only kernel to config MTU in such cases

[v2 7/7] net/dpaa: restrict MTU config for shared intf

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

Since DPDK was able to configure mtu in VSP/Shared interface  mode,
it was causing misconfiguration of the hw which further caused crashes.

This patch allow only kernel to config MTU in such cases

[PATCH v3 7/8] net/dpaa: restrict MTU config for shared intf

[vanshika.shukla]

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

Since DPDK was able to configure mtu in VSP/Shared interface  mode,
it was causing misconfiguration of the hw which further caused crashes.

This patch allow only kernel to config MTU in such cases

[v5 7/8] net/dpaa: restrict MTU config for shared intf

[vanshika.shukla]

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

Since DPDK was able to configure mtu in VSP/Shared interface  mode,
it was causing misconfiguration of the hw which further caused crashes.

This patch allow only kernel to config MTU in such cases
