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.

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'.

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

Provide 2 files on the debugfs:
- "rxon": write channel (1..4) to open Rx on it, 0 to rxoff
- "tx_mgmt": write binary frame, starting from MAC header

one need to care about turning receiver on/off before/after tx_mgmt

Correct sequence is:
 echo $channel > rxon
 cat mfmt_frame > tx_mgmt
 echo 0 > rxon
