There is a general pattern here that the flag has a name derived from
the capability. Except you dropped the WOL_WOF here. It would probably
be better to not have WOL_WOF at all.

Indeed, I did that because the global 2 register 0x0D "Switch
MAC/WoL/WoF" is used to indirectly configure the switch MAC address, the
Wake on Lan and Wake on Frame. So I explicitly named the capability
MV88E6XXX_CAP_SWITCH_MAC_WOL_WOF and the flag for the switch MAC
MV88E6XXX_FLAG_SWITCH_MAC.

So if we add support for WoL, we can then define:

    #define MV88E6XXX_FLAG_WOL BIT(MV88E6XXX_CAP_SWITCH_MAC_WOL_WOF)

But I can get rid of it if it feels confusing.

Thanks,
