Intel Wired LAN Driver Updates 2019-06-28

This series contains a smorgasbord of updates to many of the Intel
drivers.

Gustavo A. R. Silva updates the ice and iavf drivers to use the
strcut_size() helper where possible.

Miguel increases the pause and refresh time for flow control in the
e1000e driver during reset for certain devices.

Dann Frazier fixes a potential NULL pointer dereference in ixgbe driver
when using non-IPSec enabled devices.

Colin Ian King fixes a potential overflow during a shift in the ixgbe
driver.  Also fixes a potential NULL pointer dereference in the iavf
driver by adding a check.

Venkatesh Srinivas converts the e1000 driver to use dma_wmb() instead of
wmb() for doorbell writes to avoid SFENCEs in the transmit and receive
paths.

Arjan updates the e1000e driver to improve boot time by over 100 msec by
reducing the usleep ranges suring system startup.

Artem updates the igb driver register dump in ethtool, first prepares
the register dump for future additions of registers in the dump, then
secondly, adds the RR2DCDELAY register to the dump.  When dealing with
time-sensitive networks, this register is helpful in determining your
latency from the device to the ring.

Alex fixes the ixgbevf driver to use the current cached link state,
rather than trying to re-check the value from the PF.

Harshitha adds support for MACVLAN offloads in i40e by using channels as
MACVLAN interfaces.

Detlev Casanova updates the e1000e driver to use delayed work instead of
timers to run the watchdog.

Vitaly fixes an issue in e1000e, where when disconnecting and
reconnecting the physical cable connection, the NIC enters a DMoff
state.  This state causes a mismatch in link and duplexing, so check the
PCIm function state and perform a PHY reset when in this state to
resolve the issue.

em_ipt: add support for addrtype

We would like to be able to use the addrtype from tc for ACL rules and
em_ipt seems the best place to add support for the already existing xt
match. The biggest issue is that addrtype revision 1 (with ipv6 support)
is NFPROTO_UNSPEC and currently em_ipt can't differentiate between v4/v6
if such xt match is used because it passes the match's family instead of
the packet one. The first 3 patches make em_ipt match only on IP
traffic (currently both policy and addrtype recognize such traffic
only) and make it pass the actual packet's protocol instead of the xt
match family when it's unspecified. They also add support for NFPROTO_UNSPEC
xt matches. The last patch allows to add addrtype rules via em_ipt.
We need to keep the user-specified nfproto for dumping in order to be
compatible with libxtables, we cannot dump NFPROTO_UNSPEC as the nfproto
or we'll get an error from libxtables, thus the nfproto is limited to
ipv4/ipv6 in patch 03 and is recorded.

v3: don't use the user nfproto for matching, only for dumping, more
    information is available in the commit message in patch 03
v2: change patch 02 to set the nfproto only when unspecified and drop
    patch 04 from v1 (Eyal Birger)

Allow em_ipt to use addrtype for matching. Restrict the use only to

don't record it then the match family is used which can be
NFPROTO_UNSPEC. Even if we add support to mask NFPROTO_UNSPEC in
iproute2 we have to be compatible with older versions which would be
also be allowed to add NFPROTO_UNSPEC matches (e.g. addrtype after the
last patch).

Refreshing TIRs is done in order to update the TIRs with the current
state of SQs in the transport domain, so that the TIRs can filter out
undesired self-loopback packets based on the source SQ of the packet.

Representor TIRs will only receive packets that originate from their
associated vport, due to dedicated steering, and therefore will never
receive self-loopback packets, whose source vport will be the vport of
the E-Switch manager, and therefore not the vport associated with the
representor. As such, it is not necessary to refresh the representors'
TIRs, since self-loopback packets can't reach them.

Since representors only exist in switchdev mode, and there is no
scenario in which a representor will exist in the transport domain
alongside a non-representor, it is not necessary to refresh the
transport domain's TIRs upon changing the state of a representor's
queues. Therefore, do not refresh TIRs upon such a change. Achieve
this by adding an update_rx callback to the mlx5e_profile, which
refreshes TIRs for non-representors and does nothing for representors,
and replace instances of mlx5e_refresh_tirs() upon changing the state
of the queues with update_rx().

This patch changes the way the driver advertises its checksum offload
capabilities within the net device features bit mask.

Instead of advertising protocol specific checksumming capabilities
which are limited today to IPv4 and IPv6, we move to reporing
generic HW checksumming capabilities.

This will allow the network stack to let mlx5 device offload checksum
for cases where the IP header is encapsulated within another protocol
and the skb->protocol doesn't indicate one of the IP versions protocol,
specifically in the case of MPLS label encapsulating the IP header and
the skb->protocol indiciates MPLS ethertype rather than IP.

Moving the HW_CSUM reporting is required in the basic net device hw
features mask and also in the extensions (vlan and encpasulation
features) since the extensions are always multiplied by the basic
features set during the packet's traversal through the stack's tx flow.

This patch enables macvlan offloads for i40e. The idea is to use
channels as macvlan interfaces. The channels are VSIs of
type VMDQ. When the first macvlan is created, the maximum number of
channels possible are created. From then on, as a macvlan interface
is created, a macvlan filter is added to these already created
channels (VSIs).

This patch utilizes subordinate device traffic classes to make queue
groups(channels) available for an upper device like a macvlan.

Steps to configure macvlan offloads:
1. ethtool -K ethx l2-fwd-offload on
2. ip link add link ethx name macvlan1 type macvlan
3. ip addr add <address> dev macvlan1

This patch adds the RR2DCDELAY register to the ethtool registers dump.
RR2DCDELAY exists on I210 and I211 Intel Gigabit Ethernet chips and it stands
for "Read Request To Data Completion Delay". Here is how this register is
described in the I210 datasheet:

"This field captures the maximum PCIe split time in 16 ns units, which is the
maximum delay between the read request to the first data completion. This is
giving an estimation of the PCIe round trip time."

In other words, whenever I210 reads from the host memory (e.g., fetches a
descriptor from the ring), the chip measures every PCI DMA read transaction and
captures the maximum value. So it ends up containing the longest DMA
transaction time.

This register is very useful for troubleshooting and research purposes. If you
are dealing with time-sensitive networks, this register can help you get
an idea of your "I210-to-ring" latency. This helps answering questions like
"should I have PCIe ASPM enabled?" or "should I enable deep C-states?" on
my system.

It is safe to read this register at any point, reading it has no effect on
the I210 chip functionality.

the power savings of such long ranges is irrelevant due to the
