Alexander Duyck f174cdbe5b fm10k: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port
This change replaces the network device operations for adding or removing a
VXLAN port with operations that are more generically defined to be used for
any UDP offload port but provide a type.  As such by just adding a line to
verify that the offload type if VXLAN we can maintain the same
functionality.

Ngai-Mint Kwan 8998763a7b fm10k: Fix multicast mode sync issues
Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.

Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

John Fastabend 5eb4dce3b3 net: relax setup_tc ndo op handle restriction
I added this check in setup_tc to multiple drivers,

 if (handle != TC_H_ROOT || tc->type != TC_SETUP_MQPRIO)

Unfortunately restricting to TC_H_ROOT like this breaks the old
instantiation of mqprio to setup a hardware qdisc. This patch
relaxes the test to only check the type to make it equivalent
to the check before I broke it. With this the old instantiation
continues to work.

A good smoke test is to setup mqprio with,

# tc qdisc add dev eth4 root mqprio num_tc 8 \
  map 0 1 2 3 4 5 6 7 \
  queues 0@0 1@1 2@2 3@3 4@4 5@5 6@6 7@7

Alexander Duyck 09f8a82b6a fm10k: Cleanup exception handling for changing queues
This patch is meant to cleanup the exception handling for the paths where
we reset the interrupts and then reconfigure them.  In all of these paths
we had very different levels of exception handling.  I have updated the
driver so that all of the paths should result in a similar state if we
fail.

Specifically the driver will now unload the mailbox interrupt, free the
queue vectors and MSI-X, and then detach the interface.

In addition for any of the PCIe related resets I have added a check with
the hw_ready function to just make sure the registers are in a readable
state prior to reopening the interface.

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the

NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to

Jacob Keller e71c931842 fm10k: send traffic on default VID to VLAN device if we have one
This patch ensures that VLAN traffic on the default VID will go to the
corresponding VLAN device if it exists. To do this, mask the rx_ring VID
if we have an active VLAN on that VID.

For this to work correctly, we need to update fm10k_process_skb_fields
to correctly mask off the VLAN_PRIO_MASK bits and compare them
separately, otherwise we incorrectly compare the priority bits with the
cleared flag. This also happens to fix a related bug where having
priority bits set causes us to incorrectly classify traffic.

Jacob Keller 745136a8b7 fm10k: ignore invalid multicast address entries
This change fixes an issue with adding an invalid multicast address
using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2
tool and the kernel do not validate or filter the multicast addresses
when adding them to the multicast list. Thus, when synchronizing this
list with an invalid entry, the action will be aborted with an error
since the fm10k driver currently validates the list. Consequently,
multicast entries beyond the invalid one will not be processed and
communicated with the switch via the mailbox. This change makes it so
that invalid addresses will simply be skipped and allows synchronizing
the full list to proceed.

Alexander Duyck a211e0136c fm10k: Add support for PTP
This change adds support for the Linux PTP Hardware clock and timestamping
functionality provided by the hardware.  There are actually two cases that
this timestamping is meant to support.

The first case would be an ordinary clock scenario.  In this configuration
the host interface does not have access to BAR 4.  However all of the host
interfaces should be locked into the same boundary clock region and as such
they are all on the same clock anyway.  With this being the case they can
synchronize among themselves and only need to adjust the offset since they
are all on the same clock with the same frequency.

The second case is a boundary clock scenario.  This is a special case and
would require both BAR 4 access, and a means of presenting a netdev per
boundary region.  The current plan is to use DSA at some point in the
future to provide these interfaces, but the DSA portion is still under
development.

This patch takes the driver from supporting a single queue to supporting
multiple queues.  The upper queue limit for the PF is 128 queues and the
upper limit for the VF is (128 / num_vfs) rounded down to nearest power of 2.

Alexander Duyck 18283cad0a fm10k: Add interrupt support
This patch set adds interrupt support for the fm10k interfaces.  The
