Subject: r8169: PHY power-on fix
Fix extracted from Realtek's driver (8.002.00/20070713) for the PHY
attached to 8111/8168b chipsets.
The check against mac_version is just usual paranoia during the bugfix
period of the kernel cycle. -- FR
Tested on Asus M2A-VM motherboard by Roger So.
No regression on my Asrock 945G DVI either (built-in 8168 + 2x8169).

Subject: r8169: avoid needless NAPI poll scheduling
Theory : though needless, it should not have hurt.
Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP
(see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242572).
The patch makes sense in itself but I should dig why it has an effect
on #242572 (assuming that NAPI do not change in a near future).
