From: Andre Guedes <andre.guedes@intel.com>
In igc_main.c we print log messages using both dev_* and netdev_*
helpers, generating inconsistent output. Since this is a network device
driver, we should preferably use netdev_* helpers because they append
the interface name to the message, helping making sense out of the logs.
This patch converts all dev_* calls to netdev_*. There is only two
exceptions:
1) calls wihtin igc_probe (net_device has not been registered yet)
2) calls in igc_init_module (module initialization).
It also takes this opportunity to improve some messages.

Introduced igc_diag.c and igc_diag.h, these files have the
diagnostics functionality of igc driver. For the time being
these files are being used by ethtool self-test callbacks.
Which mean that eeprom, registers and link self-tests for
ethtool were implemented.

From: Andre Guedes <andre.guedes@intel.com>
In igc_ethtool.c we print log messages using dev_* helpers, generating
inconsistent output with the rest of the driver. Since this is a network
device driver, we should preferably use netdev_* helpers because they
append the interface name to the message, helping making sense the of
the logs.
This patch converts all dev_* calls to netdev_*.

Your right, these never had them, which is why it was not caught. I am fine with adding the terminating \n, if that is what is requested. Andre was just trying to fix the message to properly capitalize the first letter of the message.

What's odd is no other intel driver uses the same logging
format even though many use the same message.
Likely there's little value in capitalization.

In igc_ptp.c we print log messages using dev_* helpers, generating
inconsistent output with the rest of the driver. Since this is a network
device driver, we should preferably use netdev_* helpers because they
append the interface name to the message, helping making sense out of
the logs.
This patch converts all dev_* calls to netdev_*.

Quick note about igc_rings_dump(): This function is always called with
valid adapter->netdev so there is not need to check it.

This patch coverts one pr_debug() call to hw_dbg() in order to keep log
output aligned with the rest of the driver. hw_dbg() is actually a macro
defined in igc_hw.h that expands to netdev_dbg().
