 helper


Hi Antoine,

Its great to see macsec hw offload infrastructure happening!

Most of ndo's are named by action verbs. This ndo is abit misleading, reader
may have difficulties understanding what

+	if (phydev->drv->macsec)
+		ret = phydev->drv->macsec(phydev, macsec);

is actually doing.

May be it'd be better renaming to at least ndo_do_macsec(), or ndo_setup_macsec()
?

Similar comment is for

+struct netdev_macsec {

It reads like a macsec device context, but it is a macsec configuration command.
