HT/VHT capabilities must be reported per each band supported by a radio,
not for all bands on a radio. Furthermore, driver better not assume
any capabilities and just use whetever is reported by device itself.
To support this, convert "get channels" command into "get band info"
command. Difference is that it may also carry HT/VHT capabilities along
with channels information.
While at it, also add "num_bitrates" field to "get band info" command,
for future use.

The firmware uses a mailbox to communicate to the host what is going

Saeed Mahameed says:
====================
mlx5-updates-2017-11-04
This series includes:
From Huy: dscp to priority mapping for Ethernet packet.
===================================================
First six patches enable differentiated services code point (dscp) to
priority mapping for Ethernet packet. Once this feature is
enabled, the packet is routed to the corresponding priority based on its
dscp. User can combine this feature with priority flow control (pfc)
feature to have priority flow control based on the dscp.
Firmware interface:
Mellanox firmware provides two control knobs for this feature:
QPTS register allow changing the trust state between dscp and
pcp mode. The default is pcp mode. Once in dscp mode, firmware will
route the packet based on its dscp value if the dscp field exists.
QPDPM register allow mapping a specific dscp (0 to 63) to a
specific priority (0 to 7). By default, all the dscps are mapped to
priority zero.
Software interface:
This feature is controlled via application priority TLV. IEEE
specification P802.1Qcd/D2.1 defines priority selector id 5 for
application priority TLV. This APP TLV selector defines DSCP to priority
map. This APP TLV can be sent by the switch or can be set locally using
software such as lldptool. In mlx5 drivers, we add the support for net
dcb's getapp and setapp call back. Mlx5 driver only handles the selector
id 5 application entry (dscp application priority application entry).
If user sends multiple dscp to priority APP TLV entries on the same
dscp, the last sent one will take effect. All the previous sent will be
deleted.
The firmware trust state (in QPTS register) is changed based on the
number of dscp to priority application entries. When the first dscp to
priority application entry is added by the user, the trust state is
changed to dscp. When the last dscp to priority application entry is
deleted by the user, the trust state is changed to pcp.
When the port is in DSCP trust state, the transmit queue is selected
based on the dscp of the skb.
When the port is in DSCP trust state and vport inline mode is not NONE,
firmware requires mlx5 driver to copy the IP header to the
wqe ethernet segment inline header if the skb has it.
This is done by changing the transmit queue sq's min inline mode to L3.
Note that the min inline mode of sqs that belong to other features
such as xdpsq, icosq are not modified.
===================================================
Plus to the dscp series, some small misc changes are include as well:
From Inbar, Ethtool msglvl support and some debug prints in DCBNL logic
From Or Gerlitz, Enlarge the NIC TC offload table size
From Rabie, Initialize destination_flow struct to 0
From Feras, Add inner TTC table to IPoIB flow steering
From Tal, Enable CQE based moderation on TX CQ
====================

If the NSP port table has been refreshed, resync the representor state

The criteria that reprs cannot be replaced with another new set of reprs
has been removed. This check is not needed since the only use case that
could exercise this at the moment, would be to modify the number of
SRIOV VFs without first disabling them. This case is explicitly
disallowed in any case and subsequent patches in this series
need to be able to replace the running set of reprs.
All cases where the return code used to be checked for the
nfp_app_reprs_set function have been removed.
As stated above, it is not possible for the current code to encounter a
case where reprs exist and need to be replaced.

Recent management FW images can perform full reinit of MAC cores
without requiring a reboot. When loading the driver check if there
are changes pending and if so call NSP MAC reinit. Full application
FW reload is still required, and all MACs need to be reinited at the
same time (not only the ones which have been reconfigured, and thus
potentially causing disruption to unrelated netdevs) therefore for
now changing MAC config without reloading the driver still remains
future work.

Matthias reports:
nfp_eth_set_bit_config() is marked as __always_inline to allow gcc to
identify the 'mask' parameter as known to be constant at compile time,
which is required to use the FIELD_GET() macro.
The forced inlining does the trick for gcc, but for kernel builds with
clang it results in undefined symbols:
drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.o: In function
`__nfp_eth_set_aneg':
drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x787):
undefined reference to `__compiletime_assert_492'
drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x7b1):
undefined reference to `__compiletime_assert_496'
These __compiletime_assert_xyx() calls would have been optimized away
if
the compiler had seen 'mask' as a constant.
Add a macro to extract the mask and shift and pass those to
nfp_eth_set_bit_config() separately.

Following steps are taken in the driver to offload an XDP program:
XDP_SETUP_PROG:
* prepare:
- allocate program state;
- run verifier (bpf_analyzer());
- run translation;
* load:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
* clean up:
- free program image.
With new infrastructure the flow will look like this:
BPF_OFFLOAD_VERIFIER_PREP:
- allocate program state;
BPF_OFFLOAD_TRANSLATE:
- run translation;
XDP_SETUP_PROG:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
BPF_OFFLOAD_DESTROY:
- free program image.
Take advantage of the new infrastructure. Allocation of driver
metadata has to be moved from jit.c to offload.c since it's now
done at a different stage. Since there is no separate driver
private data for verification step, move temporary nfp_meta
pointer into nfp_prog. We will now use user space context
offsets.

We currently create a fake cls_bpf offload object when we want
to offload XDP. Simplify and clarify the code by moving the
TC/XDP specific logic out of common offload code. This is easy
now that we don't support legacy TC actions. We only need the
bpf program and state of the skip_sw flag.
Temporarily set @code to NULL in nfp_net_bpf_offload(), compilers
seem to have trouble recognizing it's always initialized. Next
patches will eliminate that variable.

Make use of the swap macro and remove unnecessary variables skb and cnt.
This makes the code easier to read and maintain.
This code was detected with the help of Coccinelle.

We can now build this driver on ARM, so I ran into a randconfig build
warning that presumably had existed on powerpc already.
drivers/net/ethernet/freescale/dpaa/dpaa_eth.c: In function 'sg_fd_to_skb':
drivers/net/ethernet/freescale/dpaa/dpaa_eth.c:1712:18: error: 'skb' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I'm slightly changing the logic here, to make it obvious to the
compiler that 'skb' is always initialized.
