Hi Sean,

These changes prevent MAC2 from probing on T2080RDB due to insufficient FMan hardware resources.

fsl-fman ffe400000.fman: set_num_of_tasks: Requested num_of_tasks and extra tasks pool for fm0 exceed total num_of_tasks.
fsl_dpa: dpaa_eth_init_tx_port: fm_port_init failed
fsl_dpa: probe of dpaa-ethernet.5 failed with error -11

The distribution of resources depends on the port type, and different FMan hardware revisions have different amounts of resources.

The current distribution of resources can be reconsidered, but this change should be reverted for now.

Regards,
Camelia
