- switch to dev/rtl8169.c from pci/if_re.c.
- enable re@cardbus. both of re@pci and re@cardbus seem to work for me.

- *
- * Written by Bill Paul <wpaul@windriver.com>
- * Senior Networking Software Engineer
- * Wind River Systems
- */
-
-/*
- * This driver is designed to support RealTek's next generation of
- * 10/100 and 10/100/1000 PCI ethernet controllers. There are currently
- * four devices in this family: the RTL8139C+, the RTL8169, the RTL8169S
- * and the RTL8110S.
- *
- * 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 7.5K, so the max MTU possible with this
- * driver is 7500 bytes.
