Recent changes in the mvneta driver reworked allocation
and handling of the ingress buffers to use entire pages.
Apart from that in SW BM scenario the HW must be informed
via PRXDQS about the biggest possible incoming buffer
that can be propagated by RX descriptors.
The BufferSize field was filled according to the MTU-dependent
pkt_size value. Later change to PAGE_SIZE broke RX operation
when usin 64K pages, as the field is simply too small.
This patch conditionally limits the value passed to the BufferSize
of the PRXDQS register, depending on the PAGE_SIZE used.
On the occasion remove now unused frag_size field of the mvneta_port
structure.

Create a net bridge, add eth and vnet to the bridge. The vnet is used
by a virtual machine. When ping the virtual machine from the outside
host and the virtual machine send multicast at the same time, the ping
package will lost.
The multicast package send to the eth, eth will send it to the bridge too,
and the bridge learn the mac of eth. When outside host ping the virtual
mechine, it will match the promisc entry of the eth which is not expected,
and the bridge send it to eth not to vnet, cause ping lost.
So this patch change promisc tcam entry position to the END of 512 tcam
entries, which indicate lower priority. And separate one promisc entry to
two: mc & uc, to avoid package match the wrong tcam entry.

Currently the driver issues 2 mmio reads to figure out the number of
transmitted packets and clean them. We can get rid of the expensive
reads since BIT 31 of the Tx descriptor can be used for that.
We can also remove the budget counting of Tx completions since all of
the descriptors are not deliberately processed.

Running pktgen with packets sizes > 512b ends up in the interface Txq
getting stuck.
"netsec 522d0000.ethernet eth0: netsec_netdev_start_xmit: TxQFull!"
appears on dmesg but the interface never recovers. It requires an
ifconfig down/up to make the interface usable again.
The reason that triggers this, is a race condition between
.ndo_start_xmit and the napi completion. The available budget is
calculated first and indicates the queue is full. Due to a costly
netif_err() the queue is not stopped in time while the napi completion
runs, clears the irq and frees up descriptors, thus the queue never wakes
up again.
Fix this by moving the print after stopping the queue, make the print
ratelimited, add barriers and check for cleaned descriptors..

This is pointless as these will be always non-NULL, since the

we wrap such changes with roce enable/disable either directly or through

Towards changing this exclusion, we need to make sure that roce will not

Under uplink LAG, packets that match a flow might arrive on both uplink
ports and transmitted through both as part of supporting aggregation and
high-availability.
When the netdevs representing the uplinks are set into LAG (bonding,
teaming), duplicate the TC flow offloading into each of the per-uplink
e-switches.
Duplication is not required if the source is the bond device, since in
this case it is assumed that the bond and the uplink netdevs share the
same TC block, and thus duplication will occur naturally by the stack.
Note that under encapsulation scheme, both flows will use the same
neighbour and hence both will contribute to the last-used feedback
towards the stack.

Assign a counter dev attribute according to device capability and use
it for management of counters related to offloaded eswitch TC flows.
With upcoming support for uplink LAG, we have two HW rules per one
logical SW (TC) rule. Although the HW supports attaching one counter
to multiple rules, we are allocating counter per HW rule.
We need this separation for two reasons:
1. "flow eswitch" counter affinity HW require the counter to be
allocated on the device where the eswitch rule is set.
2. for some use-cases (multi-path routing) each HW flow relates to
different neighbour, hence our neigh update logic must have a per-rule
HW accountant in order to provide the proper feedback to the kernel.

Under uplink LAG or multipath schemes, traffic that matches one flow
might arrive on both uplink ports and transmitted through both
as part of supporting aggregation and high-availability.
To cope with the fact that the SW model might use logical SW port
(e.g uplink team or bond) but we have two HW ports with e-switch on
each, there are cases where in order to offload a SW TC rule we
need to duplicate it to two HW flows.
Since each HW rule has its own counter we also aggregate the counter
of both rules when a flow stats query is executed from user-space.
Introduce the changes for the different elements (add/delete/stats),
currently nothing is duplicated.

In the sriov offloads mode, packets that are not matched by any
other rule are sent towards the e-switch vport manager for further
processing.
Under upcoming patches (e.g for uplink LAG), packets sent from VF
vports belonging to esw0 (e-switch related to PF0) might end up in
esw1 (e-switch related to PF1) due to muxing logic applied by the
FW.
In such a case we still want the missed packet to be sent to the

Merge tag 'mlx5-fixes-2018-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
mlx5-fixes-2018-12-13
Subject: [pull request][net 0/9] Mellanox, mlx5 fixes 2018-12-13
Saeed Mahameed says:
====================
This series introduces some fixes to the mlx5 core and mlx5e netdevice
driver.
=======
Conflict with net-next: When merged with net-next this series will
cause a moderate conflict:
1) in drivers/net/ethernet/mellanox/mlx5/core/en_tc.c (2 hunks)
Take hunks from net only and just replace *attr->mirror_count to *attr->split_count
1.1) there is one more instance of slow_attr->mirror_count to be replaced
with slow_attr->split_count, it doesn't appear in the conflict, it will
cause a compilation error if left out.
2) in mlx5_ifc.h, take hunks only from net.
Example for the merge resolution can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git/commit/?h=merge/mlx5-fixes&id=48830adf29804d85d77ed8a251d625db0eb5b8a8
branch merge/mlx5-fixes of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
(I simply merged this pull request tag into net-next and resolved the conflict)
I don't know if it's ok with you, but to save your time, you can just:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux merge/mlx5-fixes
Into net-next, before your next net merge, and you will have a clean
merge of net into net-next (at least for mlx5 files).
======
Please pull and let me know if there's any problem.

On NETDEV_PRE_CHANGEADDR, if the change is related to a RIF interface,
verify that it satisfies the criterion that all RIF interfaces have the
same MAC address prefix, as indicated by mlxsw_sp.mac_mask.
Additionally, besides explicit address changes, check that the address
of an interface for which a RIF is about to be added matches the
required pattern as well.

The Spectrum hardware demands that all router interfaces in the system
have the same first 38 resp. 36 bits of MAC address: the former limit
holds on Spectrum, the latter on Spectrum-2. Add a field that refers to
the required prefix mask and initialize in mlxsw_sp1_init() and
mlxsw_sp2_init().
