Subject: Re: [PATCH net] net: dsa: sja1105: fix port mirroring for P/Q/R/S

Hi Vladimir,

I love your patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]
[also build test WARNING on sparc-next/master linus/master v5.7-rc7 next-20200529]
[cannot apply to net/master]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
