[PATCH net-next 0/9] net: dsa: cleanup EEE (part 1)

[Russell King (Oracle)]

Hi,

First part of DSA EEE cleanups.

Patch 1 removes a useless test that is always false. dp->pl will always
be set for user ports, so !dp->pl in the EEE methods will always be
false.

Patch 2 adds support for a new DSA support_eee() method, which tells
DSA whether the DSA driver supports EEE, and thus whether the ethtool
set_eee() and get_eee() methods should return -EOPNOTSUPP.

Patch 3 adds a trivial implementation for this new method which
indicates that EEE is supported.

Patches 4..8 adds implementations for .supports_eee() to all drivers
that support EEE in some form.

Patch 9 switches the core DSA code to require a .supports_eee()
implementation if DSA is supported. Any DSA driver that doesn't
implement this method after this patch will not support the ethtool
EEE methods.

Part 2 will remove the (now) useless .get_mac_eee() DSA operation.
