There have been bugs caused by HW ULP configuration settings not being
properly cleared after cable connect in V-Pro capable systems.
This caused HW to get out of sync occasionally.
The fix ensures that ULP settings are cleared in HW after
LAN cable re-connect.

Move the mapping of the head BD before the mapping of fragments.
The TOE (h/w offload) decision logic block can be also moved up
(as the TOE flag belongs to the head BD), resulting in more
localized code (TOE logic vs BD mapping code blocks).
Note that, for this h/w, the R (status) bit for the head BD of a S/G
frame needs to be written last for a reliable transmission.
For the fragmented skb case, a local variable is used to temporarily
store the status info of the first BD, replacing a BD status read.
A merge of 2 "if(do_tstamp)" blocks was also possible.

The fix in 35e2d1152b22 ("tunnels: Allow IPv6 UDP checksums to be correctly
controlled.") changed behavior for bpf_set_tunnel_key() when in use with
IPv6 and thus uncovered a bug that TUNNEL_CSUM needed to be set but wasn't.
As a result, the stack dropped ingress vxlan IPv6 packets, that have been
sent via eBPF through collect meta data mode due to checksum now being zero.
Since after LCO, we enable IPv4 checksum by default, so make that analogous
and only provide a flag BPF_F_ZERO_CSUM_TX for the user to turn it off in
IPv4 case.

In QnQ configurations like Flex-10 where the VLANs are inserted by the
ASIC, on rare occasions the HW is encountering a scenario where the
final frame length ends to be greater than what the ASIC can support.
This is because when the TXULP pulls the TX WRB to check the length
of the frame to be transmitted it also adds the size of VLANs to be
inserted by the HW to the length of the frame indicated in the WRB,
which in some cases fails the range check. This causes a UE.
Avoid this by trimming the skb length to accommodate the VLAN insertion.

When 16-bit integers are loaded on CPUs with high order native
register sizes, the CPU could use some extra ops before using them.
And currently some of the frequently used fields in the driver like
the producer and consumer indices of the queues are declared as u16.
This patch declares such fields as u32. With this change we see the
64-byte packets per second numbers improve by about 4%.

The contract between try_read() and try_write() is that when called
each processes as much data as possible. When instructed by osd_client
to skip a message, try_read() is violating this contract by returning
after receiving and discarding a single message instead of checking for
more. try_write() then gets a chance to write out more requests,
generating more replies/skips for try_read() to handle, forcing the
messenger into a starvation loop.

Otherwise we break the contract with GSO to only pass CHECKSUM_PARTIAL
skbs down. This can easily happen with UDP+IPv4 sockets with the first
MSG_MORE write smaller than the MTU, second write is a sendfile.
Returning -EOPNOTSUPP lets the callers fall back into normal sendmsg path,
were we calculate the checksum manually during copying.

Flow dissector fixes and improvements
This patch series is meant to fix and/or improve a number of items within
the flow dissector code. The main change out of all of this is that IPv4
and IPv6 fragmentation should now be handled better than it was. As a
result we should see an improvement when handling things like IP fragment
reassembly as the skbs should now only have header data in the linear
portion of the buffer while the fragments will only hold payload data.

It turns out that for IPv4 we were reporting the ip_proto of the fragment,
and for IPv6 we were not. This patch updates that behavior so that we
always report the IP protocol of the fragment. In addition it takes the
steps of updating the payload offset code so that we will determine the
start of the payload not including the L4 header for any fragment after the
first.

This patch corrects the logic for the IPv4 parsing so that it is consistent
with how we handle IPv6. Specifically if we do not have the flow key
indicating we want the addresses we still may need to take a look at the IP
fragmentation bits and to see if we should stop after we have recognized
the L3 header.

QoS and VxLAN offloads support for Mellanox 100G mlx5 driver
This patch series introduces QoS IEEE dcbnl support for
PFC, ETS and max rate.
In addition we added VxLAN support and introduced a patch
that modifies the driver to report checksum complete in RX path
for all IP (tunneled and non-tunneled) traffic which is non HW LRO.
This series is applied on top of the latest mlx5_ifc and NDO fixes
we sent to the net tree:
net/mlx5e: Use static constant netdevice ndos
net/mlx5e: Remove select queue ndo initialization
net/mlx5: Use offset based reserved field names in the IFC header file
The QoS patches depend on the IFC change since they expose new fields in
the driver/firmware API. Both QoS and VxLAN patches depend on the NDO changes,
since they add new ndo entries.
Changes from V1:
- Fixed the S.O.B from "Matt" to "Matthew" to be aligned with the committer title.
- Don't populate VxLAN/dcbnl ndos for virtual functions.
- Addressed John comment on mlx5_setup_tc to be aligned with latest API changes.
- Added device ETS capability check prior query/modify ets configuration.
- Call mlx5e_dcbnl_ieee_setets_core at the end of mlx5e_create_netdev and don't
fail netdev creation in case it failed or ETS was not supported.
The series where applied on top of: ("5270c4dade09 Merge branch 'vxlan-cleanups'") +
latest mlx5 ifc and ndo fixes from net tree.

Support the ndo_setup_tc callback and the needed methods
for multi TC/UP support, and removed the default_vlan_prio
from mlx5e_priv which is always 0, it was replaced with
hardcoded "0" in the new select queue method.
For that we now create MAX_NUM_TC num of TISs (one per prio)
on netdevice creation instead of priv->params.num_tc which
was always 1.
So far each channel had a single TXQ, Now each channel has a
TXQ per TC (Traffic Class).
Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS,
set/get dcbx and registers the mlx5e dcbnl ops.
We still use the kernel's default TXQ selection method to select the
channel to transmit through but now we use our own method to select
the TXQ inside the channel based on VLAN priority.
In mlx5, as opposed to mlx4, tc group N gets lower priority than
tc group N+1.
