From: Lipeng <lipeng321@xxxxxxxxxx>
When register/unregister ae_dev, ae_dev should match all client
in the client_list. Enet and roce can co-exists together so we
should continue checking for enet and roce presence together.
So break should not be there.
Above caused problems in loading and unloading of modules.
Fixes: 38eddd126772 ("net: hns3: Add support of the HNAE3 framework")
