Configure unicast and multicast hardware queues for the PPE
ports to enable packet forwarding between the ports.
Each PPE port is assigned with a range of queues. The queue ID
selection for a packet is decided by the queue base and queue
offset that is configured based on the internal priority and
the RSS hash value of the packet.

Hi Luo Jie,
This appears to duplicate the initialisation of .ucastq_end.
Should the line above initialise .mcastq_end instead?
Likewise for other elements of this array.
Flagged by W=1 builds with both clang-19 and gcc-14.
Thanks for pointing to this. I will update the code and build the
patches with latest GCC version gcc-14 flagged by W=1 to check the
patches.
