*/

43/*
* This driver is designed to support Realtek's next generation of
* 10/100 and 10/100/1000 PCI ethernet controllers. There are currently
* seven devices in this family: the RTL8139C+, the RTL8169, the RTL8169S,
* RTL8110S, the RTL8168, the RTL8111 and the RTL8101E.
*
* The 8139C+ is a 10/100 ethernet chip. It is backwards compatible
* with the older 8139 family, however it also supports a special
* C+ mode of operation that provides several new performance enhancing
* features. These include:
*
*	o Descriptor based DMA mechanism. Each descriptor represents
*	  a single packet fragment. Data buffers may be aligned on
*	  any byte boundary.
*
*	o 64-bit DMA
*
*	o TCP/IP checksum offload for both RX and TX
*
*	o High and normal priority transmit DMA rings
*
*	o VLAN tag insertion and extraction
*
*	o TCP large send (segmentation offload)
*
* Like the 8139, the 8139C+ also has a built-in 10/100 PHY. The C+
* programming API is fairly straightforward. The RX filtering, EEPROM
* access and PHY access is the same as it is on the older 8139 series
* chips.
*
* The 8169 is a 64-bit 10/100/1000 gigabit ethernet MAC. It has almost the
* same programming API and feature set as the 8139C+ with the following
* differences and additions:
*
*	o 1000Mbps mode
*
*	o Jumbo frames
*
* 	o GMII and TBI ports/registers for interfacing with copper
*	  or fiber PHYs
*
*      o RX and TX DMA rings can have up to 1024 descriptors
*        (the 8139C+ allows a maximum of 64)
*
*	o Slight differences in register layout from the 8139C+
*
* The TX start and timer interrupt registers are at different locations
* on the 8169 than they are on the 8139C+. Also, the status word in the
* RX descriptor has a slightly different bit layout. The 8169 does not
* have a built-in PHY. Most reference boards use a Marvell 88E1000 'Alaska'
* copper gigE PHY.
*
* The 8169S/8110S 10/100/1000 devices have built-in copper gigE PHYs
* (the 'S' stands for 'single-chip'). These devices have the same
* programming API as the older 8169, but also have some vendor-specific
* registers for the on-board PHY. The 8110S is a LAN-on-motherboard
* part designed to be pin-compatible with the Realtek 8100 10/100 chip.
*
* This driver takes advantage of the RX and TX checksum offload and
* VLAN tag insertion/extraction features. It also implements TX
* interrupt moderation using the timer interrupt registers, which
* significantly reduces TX interrupt load. There is also support
* for jumbo frames, however the 8169/8169S/8110S can not transmit
* jumbo frames larger than 7440, so the max MTU possible with this
* driver is 7422 bytes.
