====================
1GbE Intel Wired LAN Driver Updates 2017-08-08
This series contains updates to e1000e and igb/igbvf.
Gangfeng Huang fixes an issue with receive network flow classification,
where igb_nfc_filter_exit() was not being called in igb_down() which
would cause the filter tables to "fill up" if a user where to change
the adapter settings (such as speed) which requires a reset of the
adapter.
Cliff Spradlin fixes a timestamping issue, where igb was allowing requests
for hardware timestamping even if it was not configured for hardware
transmit timestamping.
Corinna Vinschen removes the error message that there was an "unexpected
SYS WRAP", when it is actually expected. So remove the message to not
confuse users.
Greg Edwards provides several patches for the mailbox interface between
the PF and VF drivers. Added a mailbox unlock method to be used to unlock
the PF/VF mailbox by the PF. Added a lock around the VF mailbox ops to
prevent the VF from sending another message while the PF is still
processing the previous message. Fixed a "scheduling while atomic" issue
by changing msleep() to mdelay().
Sasha adds support for the next LOM generations i219 (v8 & v9) which
will be available in the next Intel client platform IceLake.
John Linville adds support for a Broadcom PHY to the igb driver, since
there are designs out in the world which use the igb MAC and a third
party PHY. This allows the driver to load and function as expected on
these designs.

The PF driver assumes the VF will not send another mailbox message until
the PF has written its reply to the previous message. If the VF does,
that message will be silently dropped by the PF before it writes its
reply to the mailbox. This results in a VF mailbox timeout for posted
messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Add a lock around the VF mailbox ops to prevent the VF from sending
another message while the PF is still processing the previous one.

When the PF receives a mailbox message from the VF, it grabs the mailbox
lock, reads the VF message from the mailbox, ACKs the message and drops
the lock.
While the PF is performing the action for the VF message, nothing
prevents another VF message from being posted to the mailbox. The
current code handles this condition by just dropping any new VF messages
without processing them. This results in a mailbox timeout in the VM
for posted messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Given the right sequence of VF messages and mailbox timeouts, this
condition can go on ad infinitum.
Modify the PF mailbox read method to take an 'unlock' argument that
optionally leaves the mailbox locked by the PF after reading the VF
message. This ensures another VF message is not posted to the mailbox
until after the PF has completed processing the VF message and written
its reply.

Unifies adjusted and unadjusted register value types (e.g. FRAME_POINTER is
now just a PTR_TO_STACK with zero offset).
Tracks value alignment by means of tracking known & unknown bits. This
also replaces the 'reg->imm' (leading zero bits) calculations for (what
were) UNKNOWN_VALUEs.
If pointer leaks are allowed, and adjust_ptr_min_max_vals returns -EACCES,
treat the pointer as an unknown scalar and try again, because we might be
able to conclude something about the result (e.g. pointer & 0x40 is either
0 or 0x40).
Verifier hooks in the netronome/nfp driver were changed to match the new
data structures.

TSAUXC.DisableSystime is never set, so SYSTIM runs into a SYS WRAP
every 1100 secs on 80580/i350/i354 (40 bit SYSTIM) and every 35000
secs on 80576 (45 bit SYSTIM).
This wrap event sets the TSICR.SysWrap bit unconditionally.
However, checking TSIM at interrupt time shows that this event does not
actually cause the interrupt. Rather, it's just bycatch while the
actual interrupt is caused by, for instance, TSICR.TXTS.
The conclusion is that the SYS WRAP is actually expected, so the
"unexpected SYS WRAP" message is entirely bogus and just helps to
confuse users. Drop it.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never
clear. This prevented any future HW timestamping requests to succeed.
Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

After add an ethertype filter, if user change the adapter speed several
times, the error "ethtool -N: etype filters are all used" is reported by
igb driver.
In older patch, function igb_nfc_filter_exit() and igb_nfc_filter_restore()
is not paried. igb_nfc_filter_restore() exist in igb_up(), but function
igb_nfc_filter_exit() is exist in __igb_close(). In the process of speed
changing, only igb_nfc_filter_restore() is called, it will take a position
of ethertype bitmap.
Reproduce steps:
Step 1: Add a etype filter by ethtool
$ethtool -N eth0 flow-type ether proto 0x88F8 action 1
Step 2: Change the adapter speed to 100M/full duplex
$ethtool -s eth0 speed 100 duplex full
Step 3: Change the adapter speed to 1000M/full duplex
ethtool -s eth0 speed 1000 duplex full
Repeat step2 and step3, then dmesg the system log, you can find the error
message, add new ethtype filter is also failed.
This fixing is move igb_nfc_filter_exit() from __igb_close() to igb_down()
to make igb_nfc_filter_restore()/igb_nfc_filter_exit() is paired.

Core driver updates to allow selectively building the driver with

- Multi-Physical Function Switch (MPFs) support.
For that we split E-Switch and MPFs functionalities into separate files.

is taking place and until it completes.
From Rabie,
Increase the maximum supported flow counters.
