[U-Boot] [PATCH v4 0/3] net: phy: Force master mode for RTL8211C on some boards

[Michael Haas]

This patch is required to get reliable 1000BASE-T operation on some
boards using the RTL8211C(L) PHY.

Following discussions on v2 of this patch, I have removed the incorrect
check for the RTL8211C(L). Affected boards now have to define
CONFIG_RTL8211X_PHY_FORCE_MASTER to benefit from the fix.

Note that this patch requires Karsten Merkers '[PATCH] net: phy: Realtek
RTL8211B/C PHY ID fix' as well as Hans de Goede's recent u-boot-sunxi
pull request, specifically 1eae8f66ff749409eb96e2f3f3387c56232d0b8a and
fc8991c61c393ce6a9d3dfc97cb56dbbd9e8cbba.

 - Changed KCONFIG description according to Karsten Merker's suggestions
   plus some clarification of my own
 - Changed commit message according to Karsten Merker's suggestions
 - Changed commit summary according to Chen-Yu Tsai's suggestion,
   modified to fit the 70 character limit
 - Changed commit summary according to Chen-Yu Tsai's suggestion,

Changes in v3:
 - Remove incorrect detection of RTL8211CL and use #ifdef instead
   (thanks to Karsten Merker)
