[PATCH] libertas: before sleeping, check for a command result

[Holger Schurig]

The thing is: now I don't have the issue that I reported
in the first message of this thread anymore. Libertas
works as expected without the patch.

I'm on wireless-testing v2.6.26-rc3-8056-gc2c4044 and have the
following patches applied:

libertas-fix-lock.patch
libertas-fix-printk.patch
libertas-if-cs-speed-firmware.patch
libertas-if-cs-int.patch


Compared to friday, I also turned on the following kernel debug
options:

+CONFIG_DEBUG_KERNEL=y
+CONFIG_DETECT_SOFTLOCKUP=y
+CONFIG_DEBUG_PREEMPT=y
+CONFIG_DEBUG_RT_MUTEXES=y
+CONFIG_DEBUG_PI_LIST=y
+CONFIG_DEBUG_SPINLOCK=y
+CONFIG_DEBUG_MUTEXES=y
+CONFIG_DEBUG_LOCK_ALLOC=y
+CONFIG_PROVE_LOCKING=y
+CONFIG_LOCKDEP=y
+CONFIG_LOCK_STAT=y
+CONFIG_TRACE_IRQFLAGS=y
+CONFIG_DEBUG_SPINLOCK_SLEEP=y

Yet associating and executing of commands works fine. I
did run "while true; do iwconfig eth1; sleep 0.2; done"
quite long (up to sequence number 8804) and did not
have any hickup.

On friday, I even saw the hickup on the first commands/response ...
