Hello,

I was windering what is the purpose of the file
drivers/net/ethernet/samsung/sxgbe/sxgbe_xpcs.c

From git log and comments, it appears this driver is for
Samsung SoCs.

I can't find anything that refers to it, and if I remove it from the
makefile:

@@ -1,4 +1,4 @@
 obj-$(CONFIG_SXGBE_ETH) += samsung-sxgbe.o
 samsung-sxgbe-objs:= sxgbe_platform.o sxgbe_main.o sxgbe_desc.o \
                sxgbe_dma.o sxgbe_core.o sxgbe_mtl.o  sxgbe_mdio.o \
-               sxgbe_ethtool.o sxgbe_xpcs.o $(samsung-sxgbe-y)
+               sxgbe_ethtool.o $(samsung-sxgbe-y)

and then make clean and recompile, I see no bad effect.

What is the motivation for the experiment to remove it?
This file probably gets used only on Samsung SoCs.

I just wondered.  I was looking at dependencies between networking files.
This one stands out because nothing is dependenton it, even the files it
is compiled with, and it doesn't contain the usual functions,
register_netdev, etc.

Thanks for the explanation.
