drivers/net: Kconfig and Makefile cleanup
After the move of the Ethernet drivers into drivers/net/ethernet/ there was some leftover cleanup to do in the Kconfig and Makefile. Removed the 10/100, 1000, and 10GbE Kconfig menus. Removed the out-dated pci-skeleton.c file which was used an example driver. With the current networking features and structure, the file is no longer a good example to use for driver creation.

- 100BASE-T4 (100 Mbps over 4 standard voice-grade twisted pair
- cables, using hubs), 100BASE-FX (100 Mbps over optical fiber links)
- [the 100BASE varieties are also known as Fast Ethernet], and Gigabit
- Ethernet (1 Gbps over optical fiber or short copper links).
-
- If your Linux machine will be connected to an Ethernet and you have
- an Ethernet network interface card (NIC) installed in your computer,
- say Y here and read the Ethernet-HOWTO, available from

-
- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the RealTek RTL8139 series, the RealTek
-Fast Ethernet controllers for PCI and CardBus. This chip is used on many
-low-end boards, sometimes with its markings changed.
-
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS will assign the
-PCI INTA signal to a (preferably otherwise unused) system IRQ line.
-
-III. Driver operation
-
-IIIa. Rx Ring buffers
-
-The receive unit uses a single linear ring buffer rather than the more
-common (and more efficient) descriptor-based architecture. Incoming frames
-are sequentially stored into the Rx region, and the host copies them into
-skbuffs.
-
-Comment: While it is theoretically possible to process many frames in place,
-any delay in Rx processing would cause us to drop frames. More importantly,
-the Linux protocol stack is not designed to operate in this manner.
-
-IIIb. Tx operation
-
-The RTL8139 uses a fixed set of four Tx descriptors in register space.
-In a stunningly bad design choice, Tx frames must be 32 bit aligned. Linux
-aligns the IP header on word boundaries, and 14 byte ethernet header means
-that almost all frames will need to be copied to an alignment buffer.
