[dpdk-dev] [PATCH v2 00/17] cleanup logs in main PMDs

[David Marchand <david.marchand@6wind.com>]

Here is a patchset that reworks the log macro in e1000, ixgbe and i40e PMDs.
The idea behind this is to make it easier to debug some init failures and to be
sure of the datapath selected in these PMDs (rx / tx handlers selection).

The PMDs changes involve adding more debug messages in the default build.
A new eal option has been added to set the default log level, so that you can
render the eal a little less noisy.

I did not change the default log level for now, as some eal log messages are
marked as DEBUG while being interesting (from my point of view).
I suppose we can change the default log level later once the eal has been
cleaned up.

Changes since v2:
- continue clean up by always using PMD_*_LOG when logging something in
  PMD (i.e. no more printf, RTE_LOG, DEBUGOUT)
- introduce PMD_DRV_LOG_RAW macro for use by shared driver code
- adopt 'second approach': no more \n in PMD_*_LOG callers. This means that we
  will enforce a 'no \n' policy in logs for PMD.
