1GbE Intel Wired LAN Driver Updates 2019-10-29
This series contains updates to e1000e, igb, ixgbe and i40e drivers.
Sasha adds support for Intel client platforms Comet Lake and Tiger Lake
to the e1000e driver. Also adds a fix for a compiler warning that was
recently introduced, when CONFIG_PM_SLEEP is not defined, so wrap the
code that requires this kernel configuration to be defined.
Alex fixes a potential race condition between network configuration and
power management for e1000e, which is similar to a past issue in the igb
driver. Also provided a bit of code cleanup since the driver no longer
checks for __E1000_DOWN.
Josh Hunt adds UDP segmentation offload support for igb, ixgbe and i40e.

The bonding uses the L4 ports to balance flows between slaves. As the ICMP
protocol has no ports, those packets are sent all to the same device:
# tcpdump -qltnni veth0 ip |sed 's/^/0: /' &
# tcpdump -qltnni veth1 ip |sed 's/^/1: /' &
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 315, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 315, seq 1, length 64
# ping -qc1 192.168.0.2

1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 317, seq 1, length 64
But some ICMP packets have an Identifier field which is
used to match packets within sessions, let's use this value in the hash
function to balance these packets between bond slaves:
# ping -qc1 192.168.0.2
0: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 303, seq 1, length 64
0: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 303, seq 1, length 64
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 304, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 304, seq 1, length 64
Aso, let's use a flow_dissector_key which defines FLOW_DISSECTOR_KEY_ICMP,
so we can balance pings encapsulated in a tunnel when using mode encap3+4:
# ping -q 192.168.1.2 -c1
0: IP 192.168.0.1 > 192.168.0.2: GREv0, length 102: IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 585, seq 1, length 64

This patch is meant to address possible race conditions that can exist
between network configuration and power management. A similar issue was
fixed for igb in commit 9474933caf ("igb: close/suspend race in
netif_device_detach").
In addition it consolidates the code so that the PCI error handling code
will essentially perform the power management freeze on the device prior to
attempting a reset, and will thaw the device afterwards if that is what it
is planning to do. Otherwise when we call close on the interface it should
see it is detached and not attempt to call the logic to down the interface
and free the IRQs again.
From what I can tell the check that was adding the check for __E1000_DOWN
in e1000e_close was added when runtime power management was added. However
it should not be relevant for us as we perform a call to
pm_runtime_get_sync before we call e1000_down/free_irq so it should always
be back up before we call into this anyway.

40GbE Intel Wired LAN Driver Updates 2019-10-25
This series contains updates to i40e only. Several are fixes that could
go to 'net', but were intended for 'net-next'.
Sylwia changes how the driver function to read the NVM module data, so
that it is able to read the LLDP agent configuration to allow for
persistent LLDP.
Jaroslaw resolves an issue where the incorrect FEC settings were being
displayed in ethtool, by setting the proper FEC bits.
Piotr moves the hardware flags detection into a separate function, so
that the specific flags can be set based on the MAC and NVM. Also
extends the PHY access function to include a command flag to let the
firmware know it should not change the page while accessing a OSFP module.
Updates the driver to display the driver and firmware version when in
recovery mode.
Aleksandr refactored the VF MAC filters accounting since an untrusted
VF was able to delete but not add a MAC filter, so refactor the code to
have more consistency and improved logging.
Nicholas updates the driver to use a default interval of 50 usecs,
instead of the current 100 usecs which was causing some regression
performance issues.
Damian resolved LED blinking issues for X710T*L devices by adding
specific flows for these devices in the LED operations.
Navid Emamdoost found where allocated memory is not being properly freed
upon a failure in setting up MAC VLANs, so added the missing kfree().

author to respond to community feedback.
