Subject: [PATCH net-next 4/4] r8169: don't configure max jumbo frame size per
chip version
We don't have to configure the max jumbo frame size per chip
(sub-)version. It can be easily determined based on the chip family.
And new members of the RTL8168 family (if there are any) should be
automatically covered.
