Adapt the skge driver to the reworked PCI PM

* Use device_set_wakeup_enable() and friends as needed
* Remove an open-coded reference to the standard PCI PM registers
* Use pci_prepare_to_sleep() and pci_back_from_sleep() in the
  ->suspend() and ->resume() callbacks
* Use the observation that it is sufficient to call pci_enable_wake()
  once, unless it fails

Tested on Asus L5D (Yukon-Lite rev 7).

This reverts commit 7bf6bf48.

The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1.  It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.

Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.

My change

    commit e2a6b852
    net: Enable TSO if supported by at least one device

didn't do what was intended because the netdev_compute_features
function was designed for conjunctions.  So what happened was that
it would simply take the TSO status of the last constituent device.

This patch extends it to support both conjunctions and disjunctions
under the new name of netdev_increment_features.

It also adds a new function netdev_fix_features which does the
sanity checking that usually occurs upon registration.  This ensures
that the computation doesn't result in an illegal combination
since this checking is absent when the change is initiated via
ethtool.

The two users of netdev_compute_features have been converted.

The Mellanox ConnectX can operate as an InfiniBand adapter, as an
Ethernet NIC, or as a Fibre Channel (FC) HBA.  The kernel has a
low-level driver, mlx4_core, which handles multiplexing access to the
device, and there is also already an InfiniBad driver, mlx4_ib.

This patch adds a new driver, mlx4_en, which implements a standard
Ethernet NIC driver.

Multi-protocol adapters support different port types.  Each consumer
of mlx4_core queries for supported port types; in particular mlx4_ib
can no longer assume that all physical ports belong to it.  Port type
is configured through a sysfs interface.  When the type of a port is
changed, all mlx4 interfaces are unregistered, and then registered
again with the new port types.

The 8139 drivers are a source of error messages that confuse users.

Since this device can not be disambiguated by normal PCI device
id's two drivers match the same info. But the module utilities
seem to correctly handle this overlap, they try one driver, then
if that doesn't load try the other. Therefore there is no need for
a message to be logged with error level severity, just using info
level instead. Can't be completely silent because user might have
configure one driver and forgot the other one.

Commit 147e70e6 ("cxgb3: Use SKB list interfaces instead of home-grown
implementation.") causes a crash in t3_l2t_send_slow() when an iWARP
connection request is received.  This is because the new l2t_entry.arpq
skb queue is never initialized, and therefore trying to add an skb to
it causes a NULL dereference.  With the old code there was no need to
initialize the queues because the l2t_entry structures were zeroed,
and the code used NULL to mean empty.

Fix this by adding __skb_queue_head_init() when all the l2t_entry
structures get allocated.
