My NetBSD desktop's motherboard has the same chip:

wm0 at pci3 dev 0 function 0: Intel i82573L Gigabit Ethernet, rev. 0
wm0: interrupting at ioapic0 pin 17 (irq 10)
wm0: PCI-Express bus
wm0: 256 word (8 address bits) SPI EEPROM
wm0: Ethernet address 00:15:f2:xx:xx:xx
makphy0 at wm0 phy 1: Marvell 88E1111 Gigabit PHY, rev. 2

That problem is still there but IMHO not so urgent. Thanks to PCI Express
and the fast CPU driving the card TSO support isn't critical.

That problem has been fixed. Outgoing:

That's line rate.
