[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

This patch fix this problem by adding a goto statement instead
of return in case no sec device available.

[v2 7/7] 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
