After upgrading to 5.3-BETA7 from 5.2.1-RELEASE-p8, I found out that I
need debug.mpsafenet=0 with this ethernet card as well to get reliable
network connections again:

skc0: 3Com Gigabit LOM (3C940)
sk0: <Marvell Semiconductor, Inc. Yukon> on skc0
sk0: Ethernet address: 00:0c:6e:ea:f1:ba
miibus0: <MII bus> on sk0
e1000phy0: <Marvell 88E1000 Gigabit PHY> on miibus0
e1000phy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX-FDX, auto

Without debug.mpsafenet=0, web pages become broken, SSH connections get
terminated because of unexpected bytes in the TCP-stream, etc.
