Subject: r8169: fix RxMissed register access
X-Git-Tag: v2.6.28-rc1~717^2~195^2~71

r8169: fix RxMissed register access
- 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.

r8169: wake up the PHY of the 8168
This is typically needed when some other OS puts the PHY
to sleep due to the disabling of WOL options in the BIOS
of the system.
