Re: [net] net: phy: mscc: adjust the phy support for PTP and MACsec

[Antoine Tenart]

Hi Steen!

Either this is a fix and it would need a Fixes: tag in addition to the
Signed-off-by: one (you can have a look at the git history to see what
is the format); or the patch is not a fix and then it should have
[net-next] in its subject instead of [net].

Please have a look at the relevant documentation,
https://www.kernel.org/doc/html/latest/networking/netdev-FAQ.html

Thanks!
Antoine
