Yes, my fw doesn't support mesh. Will it cause trouble if I use this driver?

After I upgrade to the driver from wireless-testing, I got:
libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman
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 0x00a3 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: eth1: Marvell WLAN 802.11 adapter

And the performance seems a little better.
