Technical description
In the Linux kernel, the following vulnerability has been resolved:
nfp: clean mc addresses in application firmware when closing port

cleaned in software while not removed from application firmware. Thus
the mc addresses are remained and will cause resource leak.
Now use `__dev_mc_unsync` to clean mc addresses when closing port.
