On 1st sight, logs look fine:

[21:52:52] <lautriv> [    6.050967] ieee80211 phy0: 88w8361p v4,
00173f3bdde3, STA firmware 2.1.4.25

But WLAN connection is not that fast and stable as lautriv reports
(several abnormalities were observed).

I requested a tarball which includes:
* dmesg (Linux-3.3.3)
* e_n_a (/etc/network/interfaces)
* ifconfig output
* iwconfig output
* iw_phy output
* ps_axu (WPA) output

lautriv will be so kind to be around on #linux-wireless/Freenode the
next days (UTC+2: German/Swiss local-time).
Just ping him.

Hope you have fun, together!

A new tarball from lautriv with same outputs as before, but now tested
with Linux-3.4-rc4.

The output looks good enough for me to ACK adding the PCI ID.

Can the firmware being used here be submitted to the linux-firmware
git tree?

So Marvell sent John a driver for TopDog a long time ago, which he put
up on kernel.org.  That driver was reworked by Louis and put up in a git
tree, but both were lost to the kernel.org hack.  I have git backups of
both git trees.  I put Louis' cleanup here:

http://people.redhat.com/dcbw/mrvl_cb82.tar.bz2

That driver (mrvl_cb82) has the following PCI IDs:

static const struct pci_device_id mwl_id_tbl[] __devinitdata = {
        { PCI_VDEVICE(MARVELL, 0x2a02), 0 },
        { PCI_VDEVICE(MARVELL, 0x2a03), 1 },
        { PCI_VDEVICE(MARVELL, 0x2a06), 2 },
        { PCI_VDEVICE(MARVELL, 0x2a07), 3 },
        { PCI_VDEVICE(MARVELL, 0x2a04), 4 },
        { PCI_VDEVICE(MARVELL, 0x2a08), 5 },
        { PCI_VDEVICE(MARVELL, 0x2a0a), 6 },
        { PCI_VDEVICE(MARVELL, 0x2a0b), 7 },
        { PCI_VDEVICE(MARVELL, 0x2a0c), 8 },
        { 0 }
};

and supposedly works for CB82 + CB85.  The firmware helper for CB82
looks pretty close to the mwl8k one.

The firmware API exposed by mrvl_cb82 looks very close to mwl8k
actually.  I only checked the HostCmd bits, not the structures, so I
would expect a few differences.  There are some commands that mwl8k
exposes that mrvl_cb82 does not and vice versa, but I'm not sure if the
drivers actually use those commands.

Hope this helps.
