Actually, I used get_maintainer scripts and the results is as follow:
"./scripts/get_maintainer.pl -f drivers/net/ethernet/marvell/prestera/prestera_acl.c"
Taras Chornyi <tchornyi@...vell.com> (supporter:MARVELL PRESTERA ETHERNET SWITCH DRIVER)
"David S. Miller" <davem@...emloft.net> (maintainer:NETWORKING DRIVERS)
Eric Dumazet <edumazet@...gle.com> (maintainer:NETWORKING DRIVERS)
Jakub Kicinski <kuba@...nel.org> (maintainer:NETWORKING DRIVERS)
Paolo Abeni <pabeni@...hat.com> (maintainer:NETWORKING DRIVERS)
netdev@...r.kernel.org (open list:NETWORKING DRIVERS)
linux-kernel@...r.kernel.org (open list)

Therefore, I submitted my patch to the above addresses.

And this time I checked the fixes commit, and found that it has two
authors:
Signed-off-by: Volodymyr Mytnyk <vmytnyk@...vell.com>
Signed-off-by: David S. Miller <davem@...emloft.net>

Maybe there is a problem of the script that misses one.
Anyway, I have already submitted the same patch and added
"vmytnyk@...vell.com" this time.

Thanks,
Jiang
