2014-06-19wil6210: work around for platforms with broken INTxVladimir Kondratiev
There are platforms where INTx can't be routed by ACPI, this leads to pci_enable_device failure. Re-try pretending we have MSI already configured; in this case pci_enable_device do not try to configure INTx. However, MSI could still work.

2014-06-19wil6210: avoid dmesg pollution by Tx errorsVladimir Kondratiev
On Tx path, when vring for the destination not found, it was considered as error and message was printed unconditionally. However, this situation is normal after disconnect. If disconnect was while heavy traffic load, lots of Tx packets will be dropped and this would cause significant amount of prints in dmesg. Demote messages priority from 'error' to 'debug'.

2014-06-19wil6210: Tx performance monitoringVladimir Kondratiev
For performance monitoring, trace time intervals when Tx vring is idle/not idle. Use CPU cycle counter for this, because jiffies is too rough, and other precise time measurement methods involve overhead while get_cycles() should be fast. This used to provide some estimation for percentage when Tx vring was idle, i.e. when hardware is under-utilized. Estimation is not precise because of many reasons - CPU frequency scaling, grt_cycles() may be per core etc. But still, it is good estimation Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.
