net: mana: Support holes in device list reply msg

2025-03-18T10:32:15Z

According to GDMA protocol, holes (zeros) are allowed at the beginning or middle of the gdma_list_devices_resp message. The existing code cannot properly handle this, and may miss some devices in the list. To fix, scan the entire list until the num_of_devs are found, or until the end of the list.

Change mana_get_primary_netdev_rcu() to mana_get_primary_netdev(), and return the ndev with refcount held. The caller is responsible for dropping the refcount. Also drop the check for IFF_SLAVE as it is not necessary if the upper device is present.
