2008-03-13libertas: implement SSID scanning for SIOCSIWSCANHolger Schurig
After my bit scan re-writing the SIOCSIWSCAN wext ioctl no longer supported scanning for a specific SSID. However, wpa_supplicant is a possible user of this ioctl, so here is code that add's this. While passing, removed even more of the debugfs-based scanning. You can (and should) the SIOCSIWSCAN to ask for scans, so there is no need for proprietary interfaces for scanning. And, besides, the scan result couldn't be used further, e.g. not for associating.

Slightly more useful if we compare it against the sequence number of the command we have outstanding, rather than comparing the reply with itself. Doh.

2008-02-29libertas: rename/document scan_channelHolger Schurig
Rename last_scanned_channel to scan_channel, just so that a grep for struct bss_descriptor's last_scanned element doesn't show up so many positives. Also documented the variable and moved it to other scan related entries in lbs_private. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W.

2008-02-28libertas: Remove unused exportsRoland Dreier
The libertas driver exports a number of symbols with no in-tree users; remove these unused exports. lbs_reset_device() is completely unused, with no callers at all, so remove the function completely. A couple of these unused exported symbols are static, which causes the following build error on ia64 with gcc 4.2.3: drivers/net/wireless/libertas/main.c:1375: error: __ksymtab_lbs_remove_mesh causes a section type conflict drivers/net/wireless/libertas/main.c:1354: error: __ksymtab_lbs_add_mesh causes a section type conflict Signed-off-by: Roland Dreier <rolandd@cisco.com> Acked-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2008-01-28libertas: don't blindly try meshHolger Schurig
The CF card only has a very old firmware (5.0.16p0). This firmware doesn't know anything about mesh config. However, current code blindly calls mesh_config when the card is inserted. So check the firmware version before issuing this command. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: change inference about buffer size in lbs_cmd()David Woodhouse
sizeof(*cmd) is going to give the total size of the data structure that we allocated, more often than not. But the size of the command to be _sent_ could be a lot smaller, as it is in the KEY_MATERIAL and SUBSCRIBE_EVENT commands for example. So swap them round; let the caller set the _command_ size explicitly in the header, and infer the maximum response size from the data structure.

2008-01-28libertas: submit RSSI command on tx timeout, to check whether module is deadDavid Woodhouse
We don't necessarily want to reset the device on a TX timeout. But more often than not, the real cause is that the firmware has crapped itself, not just that the network is busy. So submit any harmless command, and if _that_ times out, then the error handling code will reset the module, as appropriate.

2008-01-28libertas: make lbs_submit_command always 'succeed' and set command timerDavid Woodhouse
Even if it fails, we want to wait a while and try again, with an ultimate timeout if it the condition persists. So again, just use the standard command timeout behaviour. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: discard DEFER responses to commands; let the timeout triggerDavid Woodhouse
When the firmware returns 0x0004, it wants us to try again later. We can achieve that simply by throwing out the response and letting the command timeout code kick in. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: use priv->upld_buf for command responsesDavid Woodhouse
If we don't scribble over the command we sent, then we can retry it when the firmware responds with 0x0004 (which means -EAGAIN). Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: reduce explicit references to priv->cur_cmd->cmdbufDavid Woodhouse
We have a local variable 'resp' which we use for this. So use it, instead of typing the whole thing. In preparation for actually using priv->upld_buf for the responses instead... Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: allow for PS mode to be disabled when firmware doesn't support itDavid Woodhouse
Otherwise, we go into an endless busy loop trying to enable PS mode when the command queue is empty, dealing with the error response, and then trying to enable PS mode again because the command queue is empty.... it doesn't really save much power.

2008-01-28libertas: handle HOST_AWAKE event by sending WAKEUP_CONFIRM commandDavid Woodhouse
lbs_send_confirmwake() is a bit ugly but matches the way we confirm sleep. We'll deal with that whole thing later. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: don't clear priv->dnld_sent after sending sleep confirmDavid Woodhouse
DNLD_RES_RECEIVED is a bit of a misnomer -- we never wait for the result to be received; it's purely representing the state of the TX path, and in this case the TX path is definitely busy. Of course, that means that we don't actually care about DATA_SENT vs. CMD_SENT either, but that's a can of worms for another day...

2008-01-28libertas: fix buffer handling of PS_MODE commands and responsesDavid Woodhouse
Commit 5b8845345e7385d2eb37fac22ba9ab6905988be5 (or, in case the git workflow is broken and patches get recommitted, the commit entitled 'libertas: rename and re-type bufvirtualaddr to cmdbuf' by dcbw), introduced a number of bugs where we once had a pointer to a command _payload_, but now we use the pointer to the command header instead. The fix isn't wonderfully pretty for now, but it'll get better when we finish converting all commands so the structures include the header.
