Intel Wired LAN Driver Updates 2015-02-23
This series contains updates to e1000e, igbvf, i40e and i40evf.
David adds support for i219 devices to the e1000e driver.
Jeff (me) provides two patches to cleanup igbvf, first cleans up the
whitespace issues found and the second cleans up the usage of msleep(),
min() and max() with usleep_range(), min_t() and max_t() respectively.
Kamil updates the shadow RAM read/write functions by refactoring them
to prepare for future work.
Shannon renames the debugfs command "clear_stats pf" to clear_stats port"
to clarify what the function really does.
Mitch refactors the receive routine, by splitting the receive hot path
code into two, one for packet split and one for single buffer, which
improves receive performance. Disables NAPI polling sooner when closing
the interface to fix an occasional panic during close which was
caused by the driver trying to delete and clean rings at the same time.
Also refactors reset for i40evf, since a recent change to the shutdown
flow messed up the reset flow. Since i40evf_down() now holds the
critical section lock, we cannot call it from the reset handler, which
also holds the lock.
Nicholas restricts the virtual channel opcodes should remain consistent
between updates to the opcode enum.
Neerav converts the VSI connection type to use a #define instead of
using a magic number.
Anjali updates the registers file to remove registers no longer available.
Also fixes the EMPR interrupt handling, so that we won't trigger another
EMPR when we receive an EMPR event.
Catherine cleans up the variable an_enable since it was set and never
used.
Greg fixes the netdev op that allows the operator to turn MAC/VLAN
spoof checking on and off so that it includes the flag for VLAN spoof
checking.

Under rare circumstances, after a reset, set_rx_mode might get called
while the watchdog is running, which will cause a deadlock on the
critical section lock. To correct this, add a counter and give up trying
to get the lock after fifty tries. Log a message if this happens but
don't take any other action. Because this happens after a reset, all of
the Rx filters are still in place and the device won't lose
connectivity.
We can also get stuck during shutdown, if the PF has stopped communicating
with us, or if a reset is occurring. If we can't get the lock after a reasonable
amount of time, just error out. Something else bad is happening anyway, so
adding this filter is the least of our concern right now.

A recent change to the shutdown flow messed up the reset flow. Since
i40evf_down now holds the critical section lock, we cannot call it from
the reset handler, which also holds the lock. To do so causes a deadlock
accompanied by wailing and gnashing of teeth. This is easily triggered
by running an ethtool self-test on the PF device.
Instead, we move the relevant portions of i40evf_down into the reset
handler and bend them to our will. Additionally, we can optimize the
reinit path by not deleting the MAC and VLAN filters and then adding
them back again. Instead, we just set the 'add' flag and let the
watchdog resynchronize the filter list with the PF driver. We also
reword a few messages to make them more consistent with the rest of the
driver.

Until the time a more robust versioning scheme is needed/implemented all
established virtual channel opcode values should remain consistent between
updates to the opcode enum.
This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In
its current position this opcode displaces the initial value of
I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues.
Going forward the expectation is either:
a) All future opcode additions will be added as the last element of the
enum. Once VF drivers start making use of the new commands the virtual
channel version will need to be incremented and drivers will need to
implement a simple version check whereby VF drivers can only load on
PFs with a >= version.
b) or, if needed, design and implement a more complicated API
negotiation capability.
In either case PF drivers should always maintain backwards compatibility with
earlier VF driver versions.

Split the receive hot path code into two, one for packet split and one
for single buffer. This improves receive performance since we only need
to check if the ring is in packet split mode once per NAPI poll time,
not several times per packet. The single buffer code is further improved
by the removal of a bunch of code and several variables that are not
needed. On a receive-oriented test this can improve single-threaded
throughput.
Also refactor the packet split receive path to use a fixed buffer for
headers, like ixgbe does. This vastly reduces the number of DMA mappings
and unmappings we need to do, allowing for much better performance in
the presence of an IOMMU.
Lastly, correct packet split descriptor types now that we are actually
using them.

The patch "module: fix types of device tables aliases" newly requires that
invocations of
MODULE_DEVICE_TABLE(type, name);
come *after* the definition of `name'. That is reasonable, but some
drivers weren't doing this. Fix them.

printk and friends can now format bitmaps using '%*pb[l]'. cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.
