I'm using 2.6.29-rc2 + "git diff-tree v2.6.29-rc2 wireless-testing/master --
drivers/net/wireless/libertas" + "16bit/word spi mode" and

With 9.70.3p37 firmware from Marvell. I get:

# modprobe  libertas_spi
lib80211: common routines for IEEE802.11 drivers
libertas_spi: Libertas SPI driver
libertas_spi spi2.0: firmware: requesting libertas/gspi8686_hlp.bin
libertas_spi spi2.0: firmware: requesting libertas/gspi8686.bin
libertas: 00:19:88:05:b1:59, fw 9.70.3p37, cap 0x00000303
eth1 (libertas_spi): not using net_device_ops yet
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: eth1: Marvell WLAN 802.11 adapter

and I never saw "Received CMD_RESP with invalid sequence n (expected n+1)".

With gspi8686_v9.bin and gspi8686_v9_helper.bin from linux-firmware I get

# modprobe libertas_spi
lib80211: common routines for IEEE802.11 drivers
libertas_spi: Libertas SPI driver
