* libertas: convert sleep/wake config direct commandsHolger Schurig2008-04-01
| | | | | | | | | | | | | | | | Confirm sleep event: they come very regularly, eventually several times per second. Therefore we want to send the config command as fast as possible. The old code pre-set the command in priv->lbs_ps_confirm_sleep. However, the byte sequence to be sent to the hardware is the same for all interfaces. So this patch make this an extern structure, initialized at module load time. Config wake event: normal conversion to a direct command. However, I don't know how to trigger a "HOST AWAKE" event from the firmware, so this part is untested.

* libertas: reduce debug outputHolger Schurig2008-03-27
| | | | | | | | | | | | | | | | This patch tries to make dmesg logs between different runs easier to compare by * removing the jiffies (use CONFIG_PRINTK_TIME if you need timing) * remove the line numbers, they change with each applied patch It also changes the deprecated __FUNCTION__ to __func__ to make checkpatch.pl happy.

* libertas: convert GET_LOG to a direct commandHolger Schurig2008-03-25
| | | | | | | | | | | | | | | | Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of various counters, not a sequential log). Besides the "mechanical" convertion the patch add the following logical changes: * Removes the priv->logmsg variable, it was only used in one place anyway, also don't blindly get the counters when associating. Getting the counters then the user asks via WEXT for them is good enought. * don't set wstats.discard.fragment with log.rxfrag, because the latter is a counter for successfully received packets, not for fragmented packets.

* libertas: handy function to call firmware commandsHolger Schurig2008-01-28
| | | | | | | | | | | | | | | | 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.
