This patch converts some basic cases of ethtool_sprintf() to
ethtool_puts().
The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
| ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
| ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
| ethtool_puts(&data, buffer[i].name);

The old way to do LAN reset is sending reset command to firmware. Once
firmware performs reset, it reconfigures what it needs.
In the new firmware versions, veto bit is introduced for NCSI/LLDP to
block PHY domain in LAN reset. At this point, writing register of LAN
reset directly makes the same effect as the old way. And it does not
reset MNG domain, so that veto bit does not change.
Since veto bit was never used, the old firmware is compatible with the
driver before and after this change. The new firmware needs to use with
the driver after this change if it wants to implement the new feature,
otherwise it is the same as the old firmware.

txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise
wake by passing it by reference. However, txgbe_dev_shutdown()
doesn't use this parameter at all.
wake is then passed uninitialised by txgbe_dev_shutdown()
to pci_wake_from_d3().
Resolve this problem by:
* Removing the unused parameter from txgbe_dev_shutdown()
* Removing the uninitialised variable wake from txgbe_dev_shutdown()
* Passing false to pci_wake_from_d3() - this assumes that
although uninitialised wake was in practice false (0).
I'm not sure that this counts as a bug, as I'm not sure that
it manifests in any unwanted behaviour. But in any case, the issue
was introduced by:
3ce7547e5b ("net: txgbe: Add build support for txgbe")
Flagged by Smatch as:
.../txgbe_main.c:486 txgbe_shutdown() error: uninitialized symbol 'wake'.
No functional change intended.
