r8169: Enable RX_MULTI_EN for RTL_GIGA_MAC_VER_40
The ethernet port on my ASUS A88X Pro mainboard stopped working
several times a day, with messages like these in dmesg:
AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x001e address=0x0
000000000003000 flags=0x0050]

r8169: enforce RX_MULTI_EN for the 8168f.
Same narrative as eb2dc35d99028b698cdedba4f5522bc43e576bd2 ("r8169: RxConfig
hack for the 8168evl.") regarding AMD IOMMU errors.
RTL_GIGA_MAC_VER_36 - 8168f as well - has not been reported to behave the
same.

r8169: RxConfig hack for the 8168evl.
The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards
are very prone to NETDEV watchdog problems without this change. See
https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance.
