Subject: r8169: fix RxMissed register access
From: Francois Romieu <romieu@xxxxxxxxxxxxx>
- the register is defined for the 8169 chipset only and there is
no 8169 beyond RTL_GIGA_MAC_VER_06.
- only the lower 3 bytes of the register are valid
Fixes:
1. http://bugzilla.kernel.org/show_bug.cgi?id=10180
2. http://bugzilla.kernel.org/show_bug.cgi?id=11062 (bits of)
Tested by Hermann Gausterer and Adam Huffman.
