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

such as dsa_bridge_check_vlan_range must be moved from the DSA layer to the

To do that, pass directly the bridge net_device structure down to the DSA
drivers, instead of calculating a bitmask of bridge members.

The second purpose is to prepare the replacement of the complex

[    1.062495] dm9000 8000000.ethernet: insufficient resources

[    1.073451] dm9000: probe of 8000000.ethernet failed with error -2

The reason behind is that the interrupt might be provided by a gpio
controller, not probed when dm9000 is probed, and needing the probe
deferral mechanism to apply.

Currently, the interrupt is directly taken from resources. This patch
changes this to use the more generic platform_get_irq(), which handles
the deferral.

Moreover, since commit Fixes: 7085a7401ba5 ("drivers: platform: parse

platform_get_irq(), so remove the needless code in dm9000.

For L4 checksums, we currently have bpf_l4_csum_replace() helper. It's
currently limited to handle 2 and 4 byte changes in a header and feeds the
from/to into inet_proto_csum_replace{2,4}() helpers of the kernel. When
working with IPv6, for example, this makes it rather cumbersome to deal
with, similarly when editing larger parts of a header.

Instead, extend the API in a more generic way: For bpf_l4_csum_replace(),
add a case for header field mask of 0 to change the checksum at a given
offset through inet_proto_csum_replace_by_diff(), and provide a helper
bpf_csum_diff() that can generically calculate a from/to diff for arbitrary
amounts of data.

This can be used in multiple ways: for the bpf_l4_csum_replace() only
part, this even provides us with the option to insert precalculated diffs
from user space f.e. from a map, or from bpf_csum_diff() during runtime.

bpf_csum_diff() has a optional from/to stack buffer input, so we can
calculate a diff by using a scratchbuffer for scenarios where we're
inserting (from is NULL), removing (to is NULL) or diffing (from/to buffers
don't need to be of equal size) data. Also, bpf_csum_diff() allows to

bpf: add new arg_type that allows for 0 sized stack buffer

Currently, when we pass a buffer from the eBPF stack into a helper
function, the function proto indicates argument types as ARG_PTR_TO_STACK
and ARG_CONST_STACK_SIZE pair. If R<X> contains the former, then R<X+1>
must be of the latter type. Then, verifier checks whether the buffer
points into eBPF stack, is initialized, etc. The verifier also guarantees
that the constant value passed in R<X+1> is greater than 0, so helper
functions don't need to test for it and can always assume a non-NULL
initialized buffer as well as non-0 buffer size.

This patch adds a new argument types ARG_CONST_STACK_SIZE_OR_ZERO that
allows to also pass NULL as R<X> and 0 as R<X+1> into the helper function.
Such helper functions, of course, need to be able to handle these cases
internally then. Verifier guarantees that either R<X> == NULL && R<X+1> == 0
or R<X> != NULL && R<X+1> != 0 (like the case of ARG_CONST_STACK_SIZE), any
other combinations are not possible to load.

I went through various options of extending the verifier, and introducing
the type ARG_CONST_STACK_SIZE_OR_ZERO seems to have most minimal changes

====================
GENEVE/VXLAN: Enable outer Tx checksum by default

This patch series makes it so that we enable the outer Tx checksum for IPv4
tunnels by default.  This makes the behavior consistent with how we were
handling this for IPv6.  In addition I have updated the internal flags for
these tunnels so that we use a ZERO_CSUM_TX flag for IPv4 which should
match up will with the ZERO_CSUM6_TX flag which was already in use for
IPv6.

For most network devices this should be a net gain in terms of performance
as having the outer header checksum present allows for devices to report
CHECKSUM_UNNECESSARY which we can then convert to CHECKSUM_COMPLETE in order
to determine if the inner header checksum is valid.

Below is some data I collected with ixgbe with an X540 that demonstrates
this.  I located two PFs connected back to back in two different name
spaces and then setup a pair of tunnels on each, one with checksum enabled
and one without.

The one spot where this may cause a performance regression is if the
environment contains devices that can parse the inner headers and a device
supports NETIF_F_GSO_UDP_TUNNEL but not NETIF_F_GSO_UDP_TUNNEL_CSUM.  In
the case of such a device we have to fall back to using GSO to segment the
tunnel instead of TSO and as a result we may take a performance hit as seen
below with i40e.

In addition it will be necessary to update iproute2 so that we don't
provide the checksum attribute unless specified.  This way on older kernels
which don't have local checksum offload we will default to disabling the
outer checksum, and on newer kernels that have LCO we can default to
enabling it.

I also haven't investigated the effect this will have on OVS.  However I

that Tx checksumming will become enabled by default which should be

get/set_pad_info() functionality.

The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to
store DMA/MEM buffer pointer and buffer size respectively. And in both
cases for Keystone 2 the pointer type size is 32 bit regardless of
LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally
is not expected to be defined.

Unfortunately, above commit changed buffer's pointers save/restore
code (get/set_pad_info()) and added intermediate conversation to u64
which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver
crash in RX/TX path due to "Unable to handle kernel NULL pointer"
exception. This issue was reported and discussed in [1].

Hence, fix it by partially reverting above commit and restoring

sctp: Fix port hash table size computation

Dmitry Vyukov noted recently that the sctp_port_hashtable had an error in
its size computation, observing that the current method never guaranteed
that the hashsize (measured in number of entries) would be a power of two,
which the input hash function for that table requires.  The root cause of
the problem is that two values need to be computed (one, the allocation
order of the storage requries, as passed to __get_free_pages, and two the
number of entries for the hash table).  Both need to be ^2, but for
different reasons, and the existing code is simply computing one order
value, and using it as the basis for both, which is wrong (i.e. it assumes
that ((1<<order)*PAGE_SIZE)/sizeof(bucket) is still ^2 when its not).

To fix this, we change the logic slightly.  We start by computing a goal
allocation order (which is limited by the maximum size hash table we want
to support.  Then we attempt to allocate that size table, decreasing the
order until a successful allocation is made.  Then, with the resultant
successful order we compute the number of buckets that hash table supports,
which we then round down to the nearest power of two, giving us the number
of entries the table actually supports.

I've tested this locally here, using non-debug and spinlock-debug kernels,
and the number of entries in the hashtable consistently work out to be
powers of two in all cases.
