These wrappers only do two things. Firstly, they set the frame type, which isn't necessary since lbs_hard_start_xmit() gets to see which device it belongs to anyway. Secondly, they return -EOPNOTSUPP if the device is in monitor mode. Which is a strange thing to do and will provide nasty warnings from qdisc_restart(). And lbs_hard_start_xmit() seems to have code to cope with monitor mode anyway. Signed-off-by:

Having merged the nest of functions into one, now we can clean it up and fix the error handling, and the duplication -- and at least make a start on the locking. Signed-off-by:

Make a start on reducing the number of pointless nested functions, starting with the StudlyCaps. No semantic changes (yet) -- we can sort out the now-obvious discrepancy in the failure paths in a separate commit. Signed-off-by:

It was buggy as hell anyway, since it was just spewing packets at the device when it wasn't necessarily ready for them (in the USB case, while the URB was still busy). We could probably do with a better way of flushing packets to the device _immediately_, before we stick it back into sleep mode. But we can no longer just dequeue packets directly, it seems.

It doesn't need to wait until no commands are pending anyway -- it only needs to wait until the scan is finished. We can hopefully find it something else to wait on too -- it's the only user of the cmd_pending waitqueue. Signed-off-by:

At least it doesn't oops when you attempt to read or write it now. Only when you enable it and then later turn it off. And when it's enabled I don't see how it actually works. But one fewer oops is good, for now... Signed-off-by:

All existing code which sends commands is set up to have some function called with the results, not to get data back. It's more versatile this way, and providing it with a callback function which involves memcpy() is hardly difficult. Signed-off-by:

Recently I found that that sparse by default doesn't endianness checks. So I changed my compilation habit to be make modules C=1 SUBDIRS=drivers/net/wireless/libertas CHECKFLAGS="-D__CHECK_ENDIAN__" so that I get the little-endian checks from sparse as well. That showed up a good bunch of problems. Signed-off-by:

This changes the code that is used for scanning and makes it hopefully easier to understand: * move function into logical blocks * create a bunch of lbs_scan_add_XXXX_tlv() functions, that help to create the TLV parameter of CMD_802_11_SCAN * all of them are now called from the much simpler lbs_do_scan() * no **puserscancfg double-pointers :-) Signed-off-by:

I wondered about junk bytes at the end when using "lbsdebug +hex +host" until I noticed that firmware for the CF card sends my extranous bytes. It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this are just data junk. Also, in the new lbs_cmd() where was a size miscalulation that made itself clear after fixing this bug.

Bad Holger. Always test on big-endian machines, if it's little-endian you need to be swapping to/from. Signed-off-by:

This is meaningless for non-USB devices and unimplemented in their firmware. It's somewhat dubious for USB devices too, but that's a different story. Signed-off-by:

This explains why we never noticed the corruption of checksums on outgoing packets... we weren't actually checking them either. Signed-off-by:

Using an arbitrary firmware command was actually very painful. One had to change big switch() statements in cmd.c, cmdresp.c, add structs to the big union in "struct cmd_ds_command" and add the define for the CMD_802_11_xxx to the proper place. With this function, this is now much easier. For now, it implements a blocking (a.k.a. CMD_OPTION_WAITFORRSP) way where one deals directly with command requests and response buffers. You can do everything in one place: Signed-off-by:

These functions were used in the old debugfs code for events, but as this code is now gone, there's no need to export those functions. Signed-off-by:

This patch fixes the transmission problems introduced by commit f04b3787bbce4567e28069a9ec97dcd804626ac7 I'm not sure if the dummy read is really required. The old code does it. I think it can't hurt and can possibly fix some write posting problems (hardware bugs or whatever. Who knows). Signed-off-by:

commit f04b3787bbce4567e28069a9ec97dcd804626ac7 introduced a regression for the ofdmtable writing. It incorrectly removed the writing of the high 16bits for a 32bit table write and initialized the direction identifier too late. This patch does also some cleanups to make the code much more readable and adds a few comments, so non rocket scientists are also able to understand what this address caching is all about.
