Intel Wired LAN Driver Updates 2015-09-22
This series contains updates to e1000, e1000e, igbvf, ixgbe, ixgbevf and
fm10k.
Jacob provides several updates for fm10k, which cleans up comments and
most notably a fix for a corner case issue with the PF/VF mailbox code.
The issue being fm10k_mbx_reset_work clears various states about the
mailbox, but does not clear the Tx FIFO head/tail pointers. We also
are not able to simply clear these pointers, as we would drop
untransmitted messages without error. Also adds support for extra debug
statistics, which provides the ability to see what the PF thinks the
VF mailboxes look like.
Don adds support for SFP+ in X550 and support for SCTP flow director
filters SCTP mask.
Francois Romieu dusts off the e1000 driver and removes some dead calls
to e1000_init_eeprom_params().
Toshiaki Makita provides three patches to enable TSO for stacked VLAN's
on e1000e, igbvf and ixgbevf.
Mark provides the first of several ixgbe updates. First updates the
driver to accept SFP not present error for all devices, since an SFP
can still be inserted. Adds support for SFP insertion interrupt on
X550EM devices with SPFs. Adds I2C combined operations on X550EM
(not X550) devices. Moved the setting of lan_id to before any I2C
eeprom access. Lastly, set the bit bang mode in the hardware when
performing bit banding I2C operations on X550.

bridge: don't age out externally added FDB entries
v3: Per davem review: add del_timer_sync on rocker port remove.
v2: Per Jiri review comment: add BR_DEFAULT_AGEING_TIME to defines
Siva originally proposed skipping externally added FDB entries in the bridge's
FDB garbage collection func, and moving the ageing of externally added entries
to the port driver/device. This broke rocker, since rocker didn't have a
hardware (or software) mechanism for ageing out its learned FDB entries.
This patchset reintroduces Siva's bridge driver patch to skip externally added
entries and adds support in rocker so rocker can age out its own entries.
Rocker does this using a software timer similar to the bridge's FDB garbage
collection timer. Other switchdev devices/drivers can use this software timer
method or program the device to nofity aged-out entries to the driver.
Updated switchdev.txt documentation to reflect current state-of-the-art. This
removes one more XXX todo comment in switchdev.txt.

Jamal suggested to further limit the currently allowed subset of opcodes
that may be used by a direct action return code as the intention is not
to replace the full action engine, but rather to have a minimal set that
can be used in the fast-path on things like ingress for some features
that cls_bpf supports.
Classifiers can, of course, still be chained together that have direct
action mode with those that have a full exec pass. For more complex
scenarios that go beyond this minimal set here, the full tcf_exts_exec()
path must be used.

The binding to a particular classid was so far always mandatory for
cls_bpf, but it doesn't need to be. Therefore, lift this restriction
as similarly done in other classifiers.
Only a couple of qdiscs make use of class from the tcf_result, others
don't strictly care, so let the user choose his needs (those that read
out class can handle situations where it could be NULL).
An explicit check for tcf_unbind_filter() is also not needed here, as
the previous r->class was 0, so the xchg() will return that and
therefore a callback to the qdisc's unbind_tcf() is skipped.

In commit 43388da42a49 ("cls_bpf: introduce integrated actions") we
have added TCA_BPF_FLAGS. We can also retrieve this information from
the prog, dump it back to user space as well. It's useful in tc when
displaying/dumping filter info.
Also, remove tp from cls_bpf_prog_from_efd(), came in as a conflict
from a rebase and it's unused here (later work may add it along with
a real user).
