Configure ingress and egress vport ACL rules according to
vlan and qos admin parameters.
Ingress ACL flow table rules:
1) drop any tagged packet sent from the VF
2) allow other traffic (default behavior)
Egress ACL flow table rules:
1) allow only tagged traffic with vlan_tag=vst_vid.
2) drop other traffic.

Create egress/ingress ACLs per VF vport at vport enable.
Ingress ACL:
- one flow group to drop all tagged traffic in VST mode.
Egress ACL:
- one flow group that allows only untagged traffic with
smac that is equals to the original mac (anti-spoofing).
- one flow group that allows only untagged traffic.
- one flow group that allows only smac that is equals
to the original mac (anti-spoofing).
(note: only one of the above group has active rule)
- star rule will be used to drop all other traffic.
By default no rules are generated, unless VST is explicitly requested.

* We have two types of ACL flow tables - ingress and egress.
* ACLs handle traffic sent from/to E-Switch FDB table, Ingress refers to

Fix Tunnel features and enable GSO partial for several drivers
This patch series is meant to allow us to get the best performance possible
for Mellanox ConnectX-3/4 and Broadcom NetXtreme-C/E adapters in terms of
VXLAN and GRE tunnels.
The first 3 patches address issues I found in regards to GSO_PARTIAL and
TSO_MANGLEID.
The next 4 patches go through and enable GSO_PARTIAL for VXLAN tunnels that
have an outer checksum enabled, and then enable IPv6 support where I can.
One outstanding issue is that I wasn't able to get offloads working with
outer IPv6 headers on mlx4. However that wasn't a feature that was enabled
before so it isn't technically a regression, however I believe Engineers
from Mellanox said they would look into it since they thought it should be
supported.
The last patch enables GSO_PARTIAL for VXLAN and GRE tunnels on the bnxt
driver. One piece of feedback I received on the patch was that the
hardware has globally set IPv6 UDP tunnels to always have the checksum
field computed. I plan to work with Broadcom to get that addressed so that
we only populate the checksum field if it was requested by the network
stack.
v2: Rebased patches off of latest changes to the mlx4/mlx5 drivers.
Added bnxt driver patch as I received feedback on the RFC.
v3: Moved 2 patches into series for net as they were generic fixes.
Added patch to disable GSO partial if frame is less than 2x size of MSS
There are outstanding issues as called out above that need to be
addressed, however they were present before these patches so it isn't
as if they introduce a regression. In addition gains can be easily
seen so there should be no issue with applying the driver patches while
the IPv6 mlx4_en and bnxt issues are being researched.
====================

This patch assumes that the bnxt hardware will ignore existing IPv4/v6
header fields for length and checksum as well as the length and checksum
fields for outer UDP and GRE headers.
I have been told by Michael Chan that this is working. Though this might
be somewhat redundant for IPv6 as they are forcing the checksum to be
computed for all IPv6 frames that are offloaded. A follow-up patch may be
necessary in order to fix this as it is essentially mangling the outer IPv6
headers to add a checksum where none was requested.

The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware
encapsulated tunnels. This leads to issues as it triggers warnings in
skb_checksum_help as it ends up being called as we report supporting the
segmentation but not the checksumming for IPv6 frames.
This patch corrects that and drops 2 features that don't actually need to
be supported in hw_enc_features since they are Rx features and don't
actually impact anything by being present in hw_enc_features.

>From what I can tell the ConnectX-3 will support an inner IPv6 checksum and
segmentation offload, however it cannot support outer IPv6 headers. This
assumption is based on the fact that I could see the checksum being
offloaded for inner header on IPv4 tunnels, but not on IPv6 tunnels.
For this reason I am adding the feature to the hw_enc_features and adding
an extra check to the features_check call that will disable GSO and
checksum offload in the case that the encapsulated frame has an outer IP
version of that is not 4. The check in mlx4_en_features_check could be
removed if at some point in the future a fix is found that allows the
hardware to offload segmentation/checksum on tunnels with an outer IPv6
header.

In the event that the number of partial segments is equal to 1 we don't

The copying of ring data was wrong for two cases: For a full ring
nothing got copied at all (as in that case the canonicalized producer
and consumer indexes are identical). And in case one or both of the
canonicalized (after the resize) indexes would point into the second
half of the buffer, the copied data ended up in the wrong (free) part
of the new buffer. In both cases uninitialized data would get passed
back to the caller.
Fix this by simply copying the old ring contents twice: Once to the
low half of the new buffer, and a second time to the high half.
This addresses the inability to boot a HVM guest with 64 or more
vCPUs. This regression was caused by 8620015499 (xen/evtchn:

After commit 8fa520af50 "intel_pstate: Remove freq calculation from
intel_pstate_calc_busy()" intel_pstate_get() calls get_avg_frequency()
to compute the average frequency, which is problematic for two reasons.
First, intel_pstate_get() may be invoked before the driver reads the
CPU feedback registers for the first time and if that happens,
get_avg_frequency() will attempt to divide by zero.
Second, the get_avg_frequency() call in intel_pstate_get() is racy
with respect to intel_pstate_sample() and it may end up returning
completely meaningless values for this reason.
Moreover, after commit 7349ec0470 "intel_pstate: Move
intel_pstate_calc_busy() into get_target_pstate_use_performance()"
sample.core_pct_busy is never computed on Atom, but it is used in
intel_pstate_adjust_busy_pstate() in that case too.
To address those problems notice that if sample.core_pct_busy
was used in the average frequency computation carried out by
get_avg_frequency(), both the divide by zero problem and the
race with respect to intel_pstate_sample() would be avoided.
Accordingly, move the invocation of intel_pstate_calc_busy() from
get_target_pstate_use_performance() to intel_pstate_update_util(),
which also will take care of the uninitialized sample.core_pct_busy
on Atom, and modify get_avg_frequency() to use sample.core_pct_busy
as per the above.

The promise of pretty boot splashes from firmware via BGRT was at
best only that; a promise. The kernel diligently checks to make
sure the BGRT data firmware gives it is valid, and dutifully warns
the user when it isn't. However, it does so via the pr_err log
level which seems unnecessary. The user cannot do anything about
this and there really isn't an error on the part of Linux to
correct.
This lowers the log level by using pr_notice instead. Users will
no longer have their boot process uglified by the kernel reminding
us that firmware can and often is broken when the 'quiet' kernel
parameter is specified. Ironic, considering BGRT is supposed to
make boot pretty to begin with.
