These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

When an MCC cmd is issued (via a netdev/ethtool op)
while the device is not open, the MCC CQ gets processed but the EQ
is not processed (as isr is not registered.) This can cause the EQ
to become full. So, while the device is not open, CQ must not be re-armed
to prevent EQ entries.

On some servers we see the cleaning of the RX queue finish before all
the loopback packets are sent out.  This delay allows the queues to
settle before checking for successful completion.
Also, delay completion so link has time to come back up.

This change simplifies the code by setting RX_PTHRESH to 8 for
all devices, as it was unlikely that there was any advantage to
set it at 16 for earlier cards. Additionally TX_WTHRESH is

a minimal amount of write combining when writing back descriptors.
