RTL8821F(D)(I)-VD-CG is the pin-to-pin upgrade chip from
RTL8821F(D)(I)-CG.

Add new PHY ID for this chip.
It does not support RTL8211F_PHYCR2 anymore, so remove the w/r operation
of this register.

Don't you mean 8211 instead of 8821 here?

Better add a has_phycr2 to struct rtl821x_priv. Then you have:

if (priv->has_phycr2)
	do_something_with(priv->phycr2);

And by the way, net-next is closed currently.

Sorry, It’s written error, I'll correct it in next version.

Thanks for your suggestion, I will apply this method in next version.
