>Description:
The V1.0 and V2.0 versions of the Linksys EG1032 Gigabit Ethernet PCI card are supported by the sk(4) driver. Linksys changed the chipset to the RealTek RTL-8169S in the V3.0 version of the card, but did not change the PCI device ID (0x1032). The card is captured by the sk(4) driver, instead of the appropriate re(4) driver, and produces the following errors in dmesg:

skc0: <Linksys EG1032 Gigabit Ethernet> port 0xe000-0xe0ff mem 0xdf002000-0xdf0020ff irq 10 at device 20.0 on pci0
sk0: couldn't map ports/memory
device_attach: skc0 attach returned 6

The following output from scanpci -v describes the V3.0 version of the card:

>How-To-Repeat:
On FreeBSD 6.0-RELEASE:
install a Linksys EG1032 V3.0 Gigabit Ethernet PCI card. If the re(4) driver is present, it will ignore the card. If the sk(4) driver is present, it will attempt to drive the card, but fail.
>Fix:
I have created a patch for the re(4) driver to add support for this card. However, if the sk(4) driver is loaded, it will still capture the card and the card will not operate. I don't know how to correct this. The workaround is to unload or remove the sk(4) driver.
