The adapter->pmac_id[0] item is used for primary MAC address but
this is not true for adapter->uc_list[0] as is assumed in
be_set_uc_list(). There are N UC addresses copied first from net_device
to adapter->uc_list[1..N] and then N UC addresses from
adapter->uc_list[0..N-1] are sent to HW. So the last UC address is never
stored into HW and address 00:00:00:00;00:00 (from uc_list[0]) is used
instead.

Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.
Force the UDP destination port to be the one that has been offloaded to
hardware.
Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.

Demoting simple flow steering rule priority (for DPDK) was achieved by
wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF
as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper
function for the PF and all VFs.
In function mlx4_ib_create_flow(), this change caused the main rule
creation for the PF to be wrapped, while it left the associated
tunnel steering rule creation unwrapped for the PF.
This mismatch caused rule deletion failures in mlx4_ib_destroy_flow()
for the PF when the detach wrapper function did not find the associated
tunnel-steering rule (since creation of that rule for the PF did not
go through the wrapper function).
Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native"
(so that the PF invocation does not go through the wrapper), and perform
the required priority demotion for the PF in the mlx4_ib_create_flow()
code path.

mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering
rule (which results in freeing the rule structure), and then
references a field in this struct (the qp number) when releasing the
busy-status on the rule's qp.
Since this memory was freed, it could reallocated and changed.
Therefore, the qp number in the struct may be incorrect,
so that we are releasing the incorrect qp. This leaves the rule's qp
in the busy state (and could possibly release an incorrect qp as well).
Fix this by saving the qp number in a local variable, for use after
removing the steering rule.

Under the switchdev/offloads mode, packets that don't match any
e-switch steering rule are sent towards the e-switch management
port. We use a NIC HW steering rule set per vport (uplink and VFs)
to make them be received into the host OS through the respective
vport representor netdevice.
Currnetly such missed RoCE packets will not get to this NIC steering
rule, and hence VF RoCE will not work over the slow path of the offloads
mode. This is b/c these packets will be matched by a steering rule added
by the firmware that serves RoCE traffic set on the PF NIC vport which
is also the e-switch management port under SRIOV.
Disabling RoCE on the e-switch management vport when we are in the offloads
mode, will signal to the firmware to remove their RoCE rule, and then the
missed RoCE packets will be matched by the representor NIC steering rule
as any other missed packets.
To achieve that, we disable RoCE on the PF vport. We do that by removing
(hot-unplugging) the IB device instance associated with the PF. This is
also required by our current model where the PF serves as the uplink
representor and hence only SW switching (TC, bridge, OVS) applications
and slow path vport mlx5e net-device should be running over that vport.

Pull networking fixes from David Miller:
1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar.
The most important is to not assume the packet is RX just because
the destination address matches that of the device. Such an
assumption causes problems when an interface is put into loopback
mode.
2) If we retry when creating a new tc entry (because we dropped the
RTNL mutex in order to load a module, for example) we end up with
-EAGAIN and then loop trying to replay the request. But we didn't
reset some state when looping back to the top like this, and if
another thread meanwhile inserted the same tc entry we were trying
to, we re-link it creating an enless loop in the tc chain. Fix from
Daniel Borkmann.
3) There are two different WRITE bits in the MDIO address register for
the stmmac chip, depending upon the chip variant. Due to a bug we
could set them both, fix from Hock Leong Kweh.
4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan.

There is no point in having an extra type for extra confusion. u64 is
unambiguous.
Conversion was done with the following coccinelle script:
@rem@

-typedef u64 cycle_t;
@fix@

This was entirely automated, using the script by Al:
PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
$(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)
to do the replacement at the end of the merge window.

The user prio field is wrong (and overflows) in the XDP forward
flow.
This is a result of a bad value for num_tx_rings_p_up, which should
account all XDP TX rings, as they operate for the same user prio.

Pull networking fixes from David Miller:
1) We have to be careful to not try and place a checksum after the end
of a rawv6 packet, fix from Dave Jones with help from Hannes
Frederic Sowa.
2) Missing memory barriers in tcp_tasklet_func() lead to crashes, from
Eric Dumazet.
3) Several bug fixes for the new XDP support in virtio_net, from Jason
Wang.
4) Increase headroom in RX skbs in be2net driver to accomodate
encapsulations such as geneve. From Kalesh A P.
5) Fix SKB frag unmapping on TX in mvpp2, from Thomas Petazzoni.
6) Pre-pulling UDP headers created a regression in RECVORIGDSTADDR
socket option support, from Willem de Bruijn.
7) UID based routing added a potential OOPS in ip_do_redirect() when we
see an SKB without a socket attached. We just need it for the
network namespace which we can get from skb->dev instead. Fix from
Lorenzo Colitti.

This is mostly stuff which missed the initial pull. There's a new
driver: qedi, some ufs, ibmvscsis and ncr5380 updates plus some
assorted driver fixes and also a fix for the bug where if a device
goes into a blocked state between configuration and sysfs device add
(which can be a long time under async probing) it would become
permanently blocked.
