Unfortunately after a reboot the situation is back to what it used to be before I reported success. With a second noname USB Ethernet adapter I get pretty constant 10MBit downstream throughput, with the D-Link it's an average of 5.8 MBit. I never got more than 10MBit with the noname adapter, thus I suspect that's probably a hardware imposed limit, despite its claims that it can do 100baseTX:

ugen1.2: <ADMtek> at usbus1
aue0: <ADMtek USB To LAN Converter, rev 2.00/1.01, addr 2> on usbus1
miibus2: <MII bus> on aue0
ukphy0: <Generic IEEE 802.3u media interface> PHY 1 on miibus2
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
ue1: <USB Ethernet> on aue0

This is  the dmesg output for the D-Link adapter:

ugen3.2: <vendor 0x2001> at usbus3
axe0: <vendor 0x2001 product 0x3c05, rev 2.00/0.01, addr 2> on usbus3
miibus1: <MII bus> on axe0
rlphy0: <IC Plus 10/100 PHY> PHY 3 on miibus1
rlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
ue0: <USB Ethernet> on axe0

Everything USB related from dmesg:

usbus0: 12Mbps Full Speed USB v1.0
usbus1: 480Mbps High Speed USB v2.0
usbus2: 12Mbps Full Speed USB v1.0
usbus3: 480Mbps High Speed USB v2.0
ugen0.1: <nVidia> at usbus0
uhub0: <nVidia OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0
ugen1.1: <nVidia> at usbus1
uhub1: <nVidia EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus1
ugen2.1: <nVidia> at usbus2
uhub2: <nVidia OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus2
ugen3.1: <nVidia> at usbus3
uhub3: <nVidia EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus3

I've unloaded/loaded if_axe several times to see if this remedies the throughput problem, but that failed to provide any speed improvements. I don't know what else to try, please advise!

Thanks,
