Dell Latitude D630 from 2007 has Gigabit Ethernet!

Today I looked up the specs for my 2007 Dell Latitude D630 and noticed that it supposedly supports Gigabit Ethernet.

I ran lspci and ethtool to get more info on the Ethernet controller:

[archjun@arch ~]$ ethtool -i enp9s0

[archjun@arch ~]$ lspci

09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755M Gigabit Ethernet PCI Express (rev 02)

ethtool also verifies that the speed is 1000Mb/s and indicates that the Broadcom card uses the tg3 driver.

I was unaware that my old D630 Latitude had Gigabit Ethernet because I never had the chance to connect this machine to Gigabit-capable network hardware until recently. It is ironic that this old notebook that is 8 years old has more capable Ethernet than my Lenovo S310 work laptop, which only supports up to 100Mb/s and uses the Realtek r8169 driver:
