DSA should be built as a module

Precise:

dsa: Change dsa_uses_{dsa, trailer}_tags() into inline functions
dsa: Export functions from core to modules
dsa: Combine core and tagging code
mv88e6xxx: Combine mv88e6131 and mv88e612_61_65 drivers
dsa: Define module author, description, license and aliases for drivers
dsa: Allow core and drivers to be built as modules
dsa: Remove unnecessary exports
dsa: Move all definitions needed by drivers into <net/dsa.h>
dsa: Move switch drivers to new directory drivers/net/dsa
dsa: Add reporting of silicon revision for Marvell 88E6123/88E6161/88E6165 switches.
drivers/net: dsa/mv88e6xxx.c files need linux/module.h
UBUNTU: [Config] CONFIG_NET_DSA=m

On precise, DSA is now built as a module:

$ grep CONFIG_NET_DSA /boot/config-3.2.0-26-generic
CONFIG_NET_DSA=m
CONFIG_NET_DSA_TAG_DSA=y
CONFIG_NET_DSA_TAG_EDSA=y
CONFIG_NET_DSA_TAG_TRAILER=y
CONFIG_NET_DSA_MV88E6XXX=m
CONFIG_NET_DSA_MV88E6060=m
CONFIG_NET_DSA_MV88E6XXX_NEED_PPU=y
CONFIG_NET_DSA_MV88E6131=m
CONFIG_NET_DSA_MV88E6123_61_65=m

Tagging as verified.
