MFC r241397-241399, r241409, r241493-24194.

r241397:
Remove unused item.  cxgbe's rx queue's lock was removed a long time ago.

r241398:
There is no need to report the same error twice.

r241399:
Add a driver ioctl to read a byte from any device on a port's i2c bus.
This lets userspace read arbitrary information from the SFP+ modules
etc. on this bus.

Reading multiple bytes in the same transaction isn't possible right now.
I'll update the driver once the chip's firmware supports this.

r241409:
Add a driver ioctl to clear a port's MAC statistics.

r241493:
Use global knob in the TP_PARA_REG3 register to disable congestion
drops if the user has chosen this behaviour.

r241494:
Temporary fix for kern/172364.
