* be2net: use mutex instead of spin lock for mbox_lockIvan Vecera2010-12-161-30/+45
| | | | | | | | | | Since the mbox polling uses the schedule_timeout, the mbox_lock should be a mutex and not a spin lock. The commit f25b03a replaced udelay() with schedule_timeout() but didn't change mbox_lock to semaphore or mutex. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

| | | | | | | | | | | | | The ONLINE registers can return 0xFFFFFFFF on more than one occassion. On systems that care, reading these registers could lead to problems. So the new code decides that the ASIC has encountered and error by reading the UE_STATUS_LOW/HIGH registers. AND them with the mask values and a non-zero result indicates an error.
