net/qede: restrict maximum queues for PF/VF

net/qede: fix filtering code

In qede_mac_addr_add() a check is added to differentiate between

to unicast filter table. Secondly, two separate lists will be used to keep
track of unicast/multicast mac filters to prevent duplicate filter
programming. The other change is to remove filter_config from struct
qed_eth_ops_pass and invoke the base APIs directly. This avoids the need

net/ixgbe/base: add EEE support for some PHYs

This patch adds Energy Efficient Ethernet (EEE) support for
some Marvell PHYs on some future platforms.
Because EEE capability or status was not indicated previously,
this patch simply assumes that it is supported.

As soon as there is a PHY that does not support EEE, there will
be defects in this area because the driver will not report the
EEE status correctly.

This also deletes some now-unused definitions from an earlier
Marvell PHY implementation and combines a device ID check into a
switch statement.
