Thanks, you are right. It works now. And I find it also works well
with fw 9.70.3p6.

But it is very interesting, If I disable SDIO interrupts, use polling
mode, i will get
mmc0: new SDIO card at address 0001
libertas: 00:13:e0:ab:e3:03, fw 9.70.3p6, cap 0x00000303
libertas: unidentified region code; using the default (USA)
libertas: PREP_CMD: command 0x0022 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: eth1: Marvell WLAN 802.11 adapter

And if I use enable SDIO interrupts, I will get "libertas: Command 3 timed out"
# mmc0: new SDIO card at address 0001
libertas: Command 3 timed out
libertas: 00:13:e0:ab:e3:03, fw 9.70.3p6, cap 0x00000303

libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: eth1: Marvell WLAN 802.11 adapter

Any way, it works except that message, I will looking into it.
# ./arm-linux-iperf -c 10.0.0.110 -i 10 -w 1M
