Yes, in contrast to 5.3-RC2 there are no problems (i mean ftp of 2GB 
file ~10MB/s) with 5.2.1 and:

skc0: <Marvell Gigabit Ethernet> port 0xd800-0xd8ff mem 
0xfeafc000-0xfeafffff irq 22 at device 5.0 on pci2
skc0: Yukon Gigabit Ethernet 10/100/1000Base-T Adapter
skc0: PN: Yukon 88E8001
skc0: EC: Rev. 1.3
skc0: MN: Marvell
skc0: SN: AbCdEfG334454
sk0: <Marvell Semiconductor, Inc. Yukon> on skc0
sk0: Ethernet address: 00:11:2f:54:07:95
miibus0: <MII bus> on sk0

FreeBSD 5.2.1-RELEASE-p1 #2,
GENERIC kernel, empty loader.conf, empty sysctl.conf.

So:
5.2.1 and <3Com 3C940 Gigabit Ethernet> or <Marvell Gigabit Ethernet> - 
no problem for me
5.3-RC2 and <Marvell Gigabit Ethernet> (info before) slow down under ftp 
from 10MB/s to 60KB/s

I can make aditional tests if needed.
