Intel Wired LAN Driver Updates 2018-12-20
This series contains updates to e100, igb, ixgbe, i40e and ice drivers.
I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics. This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.
Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.
Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.
YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.
Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.
Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.
Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.
Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in. This was due to the
driver not setting PME during runtime suspend.
Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

Use the mii_bus callbacks to address the entire clause 22/45 address
space. Enables userspace to poke switch registers instead of a single
PHY address.
The ixgbe firmware may be polling PHYs in a way that is not protected by
the mii_bus lock. This isn't new behavior, but as Andrew Lunn pointed
out there are more addresses available for conflicts.

Most dsa devices expect a 'struct mii_bus' pointer to talk to switches

While this works for dsa devices, it will not work safely with Linux
PHYs in all configurations since the firmware of the ixgbe device may

I210 ethernet card doesn't wakeup when a cable gets plugged. It's
because its PME is not set.
Since commit 42eca23021 ("PCI: Don't touch card regs after runtime
suspend D3"), if the PCI state is saved, pci_pm_runtime_suspend() stops
calling pci_finish_runtime_suspend(), which enables the PCI PME.
To fix the issue, let's not to save PCI states when it's runtime
suspend, to let the PCI subsystem enables PME.

Section 4.5.9 of the datasheet says that the total size of all packet
buffers combined (TxPB 0 + 1 + 2 + 3 + RxPB + BMC2OS + OS2BMC) must not
exceed 60KB. Today we are configuring a total of 62KB, so reduce the
RxPB from 32KB to 30KB in order to respect that.
The choice of changing RxPBSIZE here is mainly because it seems more
correct to give more priority to the transmit packet buffers over the
receiver ones when running in Qav mode. Also, the BMC2OS and OS2BMC
sizes are already too short.

The Watchdog workqueue in igb driver is scheduled every 2s for each
network interface. That includes updating a statistics protected by
spinlock. Function igb_update_stats in this case will be protected
against preemption. According to number of a statistics registers
(cca 60), processing this function might cause additional cpu load
on CPU0.
In case of statistics spinlock may be replaced with mutex, which
reduce latency on CPU0.

When the VF driver does a reset, it (at least the Linux one) writes to
the VFCTRL register to issue a reset and then immediately sends a reset
message using the mailbox API. This is racy because when the PF driver
detects that the VFCTRL register reset pin has been asserted, it clears
the mailbox memory. Depending on ordering, the reset message sent by
the VF could be cleared by the PF driver. It then responds to the
cleared message with a NACK which causes the VF driver to malfunction.
Fix this by deferring clearing the mailbox memory until the reset
message is received.

While reviewing code, I noticed that Eric Dumazet recommends that
drivers check the return code of napi_complete_done, and use that
to decide to enable interrupts or not when exiting poll. One of
the Intel drivers was already fixed (ixgbe).
Upon looking at the Intel drivers as a whole, we are handling our
polling and NAPI exit in a few different ways based on whether we
have multiqueue and whether we have Tx cleanup included. Several
drivers had the bug of exiting NAPI with return 0, which appears
to mess up the accounting in the stack.
Consolidate all the NAPI routines to do best known way of exiting
and to just mostly look like each other.
1) check return code of napi_complete_done to control interrupt enable
2) return the actual amount of work done.
3) return budget immediately if need NAPI poll again
Tested the changes on e1000e with a high interrupt rate set, and
it shows about an 8% reduction in the CPU utilization when busy
polling because we aren't re-enabling interrupts when we're about
to be polled.

40GbE Intel Wired LAN Driver Updates 2018-11-14
This series contains updates to i40e and virtchnl.
Lance Roy updates i40e to use lockdep_assert_held() instead of
spin_is_locked(), since it is better suited to check locking
requirements.
Jan improves the code readability in XDP by adding the use of a local
variable. Provides protection on methods that create/modify/destroy
VF's via locking mechanism to prevent unstable behaviour and potential
kernel panics.
Krzysztof adds a hardware capability flag to indicate whether firmware
supports stopping the LLDP agent.
Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer
is NULL terminated.
Mitch fixes the issue of trying to start nway on devices that do not
support auto-negotiation, by checking the autoneg state before
attempting to restart nway.
Alice updates virtchnl to keep the checks all together for ease of
readability and consistency. Also fixed a "off by one" error in the
number of traffic classes being calculated.
Richard fixed VF port VLANs, where the priority bits were incorrectly
set because the incorrect shift and mask bits were being used.
Alan adds a bit to set and check if a timeout recovery is already
pending to prevent overlapping transmit timeout recovery.

If a TX hang occurs, we attempt to recover by incrementally resetting.
If we're starved for CPU time, it's possible the reset doesn't actually
complete (or even fire) before another tx_timeout fires causing us to
fly through the different resets without actually doing them.
This adds a bit to set and check if a timeout recovery is already
pending and, if so, bail out of tx_timeout. The bit will get cleared at
the end of i40e_rebuild when reset is complete.

The i40e driver complains about unprivileged VFs trying to configure
promiscuous mode each time a VF reset occurs. This isn't the fault of
the poor VF driver - the PF driver itself is making the request.
To fix this, skip the privilege check if the request is to disable all
promiscuous activity. This gets rid of the bogus message, but doesn't
affect privilege checks, since we really only care if the unprivileged
VF is trying to enable promiscuous mode.
