SFC9000-family boards do not all use MDIO PHYs, so we need a different
test for PHY aliveness.
Introduce a PHY operation test_alive(). For PHYs attached to Falcon,
use a common implementation based on the existing PHY MDIO test.
For PHYs managed through MCDI, use the appropriate MCDI request.
Change test name in ethtool from 'core mdio' to 'phy alive'.
Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

This driver is for CAN interface cards based on the PLX90xx PCI bridge.
Driver supports now:
- Adlink PCI-7841/cPCI-7841 card (http://www.adlinktech.com/)
- Adlink PCI-7841/cPCI-7841 SE card
- Marathon CAN-bus-PCI card (http://www.marathon.ru/)
- TEWS TECHNOLOGIES TPMC810 card (http://www.tews.com/)
Changes since v1:
- Added some defines for static inline int plx_pci_check_sja1000(...)
- static struct pci_device_id plx_pci_tbl[] replaced by
static DEFINE_PCI_DEVICE_TABLE(plx_pci_tbl)
- Typo fixed

ChangeLog:
Implement .reset_resume support to retain a live network connection
during suspend despite USB power loss.
- rework operation to reference cached data in mcs7830_data and
netdev->dev_addr
- update netdev->dev_addr only in case new MAC was set successfully
. Tests done:
. ethtool -d pre-/post-suspend: register values match
. running ssh session suspend, resume: works
. ifdown device, suspend, resume: works
. ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1
after card replug works)
. verified identical MAC in ifconfig post-resume
(ok, should be verified on network side to be fully certain...)
Keywords: suspend resume network connection dead interface down

virtio_net receives packets from its pre-allocated vring buffers, then it
delivers these packets to upper layer protocols as skb buffs. So it's not
necessary to pre-allocate skb for each mergable buffer, then frees extra
skbs when buffers are merged into a large packet. This patch has deferred
skb allocation in receiving packets for both big packets and mergeable buffers
to reduce skb pre-allocations and skb frees. It frees unused buffers by calling
detach_unused_buf in vring, so recv skb queue is not needed.

There's currently no way for a virtio driver to ask for unused
buffers, so it has to keep a list itself to reclaim them at shutdown.
This is redundant, since virtio_ring stores that information. So
add a new hook to do this.

In commit 20dd3850bc "can: Speed up CAN frame
receiption by using ml_priv" the formerly used hlist of receiver lists for
each CAN netdevice has been replaced.
The hlist content ensured only CAN netdevices to be accessed by the
can_rx_(un)register() functions which accidently dropped away together with
the hlist receiver implementation.
This patch re-introduces the check for CAN netdevices in can_rx_(un)register().

This adds an additional queuing strategy, called pfifo_head_drop,
to remove the oldest skb in the case of an overflow within the queue -
the head element - instead of the last skb (tail). To remove the oldest
skb in congested situations is useful for sensor network environments
where newer packets reflect the superior information.

I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
(as it should), and unregistering involves rcu barriers by itself
So it looks nothing should be done.
