Heiner Kallweit 7c53a72245 r8169: don't use MSI-X on RTL8168g
There have been two reports that network doesn't come back on resume
from suspend when using MSI-X. Both cases affect the same chip version
(RTL8168g - version 40), on different systems. Falling back to MSI
fixes the issue.
Even though we don't really have a proof yet that the network chip
version is to blame, let's disable MSI-X for this version.

Jisheng Zhang 0f5c6c30a0 net: mvneta: fix mvneta_config_rss on armada 3700
The mvneta Ethernet driver is used on a few different Marvell SoCs.
Some SoCs have per cpu interrupts for Ethernet events, the driver uses
a per CPU napi structure for this case. Some SoCs such as armada 3700
have a single interrupt for Ethernet events, the driver uses a global
napi structure for this case.

Current mvneta_config_rss() always operates the per cpu napi structure.
Fix it by operating a global napi for "single interrupt" case, and per
cpu napi structure for remaining cases.

Toshiaki Makita 638264dc90 veth: Support per queue XDP ring
Move XDP and napi related fields from veth_priv to newly created veth_rq
structure.

When xdp_frames are enqueued from ndo_xdp_xmit and XDP_TX, rxq is
selected by current cpu.

When skbs are enqueued from the peer device, rxq is one to one mapping
of its peer txq. This way we have a restriction that the number of rxqs
must not less than the number of peer txqs, but leave the possibility to
achieve bulk skb xmit in the future because txq lock would make it
possible to remove rxq ptr_ring lock.

v3:
- Add extack messages.
- Fix array overrun in veth_xmit.

Toshiaki Makita d1396004dd veth: Add XDP TX and REDIRECT
This allows further redirection of xdp_frames like

 NIC   -> veth--veth -> veth--veth
 (XDP)          (XDP)         (XDP)

The intermediate XDP, redirecting packets from NIC to the other veth,
reuses xdp_mem_info from NIC so that page recycling of the NIC works on
the destination veth's XDP.
In this way return_frame is not fully guarded by NAPI, since another
NAPI handler on another cpu may use the same xdp_mem_info concurrently.
Thus disable napi_direct by xdp_set_return_frame_no_direct() during the
NAPI context.

v8:
- Don't use xdp_frame pointer address for data_hard_start of xdp_buff.

v4:
- Use xdp_[set|clear]_return_frame_no_direct() instead of a flag in
  xdp_mem_info.

v3:
- Fix double free when veth_xdp_tx() returns a positive value.
- Convert xdp_xmit and xdp_redir variables into flags.

Toshiaki Makita af87a3aa1b veth: Add ndo_xdp_xmit
This allows NIC's XDP to redirect packets to veth. The destination veth
device enqueues redirected packets to the napi ring of its peer, then
they are processed by XDP on its peer veth device.
This can be thought as calling another XDP program by XDP program using
REDIRECT, when the peer enables driver XDP.

Note that when the peer veth device does not set driver xdp, redirected
packets will be dropped because the peer is not ready for NAPI.

v4:
- Don't use xdp_ok_fwd_dev() because checking IFF_UP is not necessary.
  Add comments about it and check only MTU.

v2:
- Drop the part converting xdp_frame into skb when XDP is not enabled.
- Implement bulk interface of ndo_xdp_xmit.
- Implement XDP_XMIT_FLUSH bit and drop ndo_xdp_flush.

Toshiaki Makita 9fc8d518d9 veth: Handle xdp_frames in xdp napi ring
This is preparation for XDP TX and ndo_xdp_xmit.
This allows napi handler to handle xdp_frames through xdp ring as well
as sk_buff.

v8:
- Don't use xdp_frame pointer address to calculate skb->head and
  headroom.

v7:
- Use xdp_scrub_frame() instead of memset().

v3:
- Revert v2 change around rings and use a flag to differentiate skb and
  xdp_frame, since bulk skb xmit makes little performance difference
  for now.

v2:
- Use another ring instead of using flag to differentiate skb and
  xdp_frame. This approach makes bulk skb transmit possible in
  veth_xmit later.
- Clear xdp_frame feilds in skb->head.
- Implement adjust_tail.

Oversized packets including GSO packets can be dropped if XDP is
enabled on receiver side, so don't send such packets from peer.

Toshiaki Makita 948d4f214f veth: Add driver XDP
This is the basic implementation of veth driver XDP.

Incoming packets are sent from the peer veth device in the form of skb,
so this is generally doing the same thing as generic XDP.

This itself is not so useful, but a starting point to implement other
useful veth XDP features like TX and REDIRECT.

This introduces NAPI when XDP is enabled, because XDP is now heavily
relies on NAPI context. Use ptr_ring to emulate NIC ring. Tx function
enqueues packets to the ring and peer NAPI handler drains the ring.

Currently only one ring is allocated for each veth device, so it does
not scale on multiqueue env. This can be resolved by allocating rings
on the per-queue basis later.

Note that NAPI is not used but netif_rx is used when XDP is not loaded,
so this does not change the default behaviour.

v6:
- Check skb->len only when allocation is needed.
- Add __GFP_NOWARN to alloc_page() as it can be triggered by external
  events.

v3:
- Fix race on closing the device.
- Add extack messages in ndo_bpf.

v2:
- Squashed with the patch adding NAPI.
- Implement adjust_tail.
- Don't acquire consumer lock because it is guarded by NAPI.
- Make poll_controller noop since it is unnecessary.
- Register rxq_info on enabling XDP rather than on opening the device.

Manish Chopra 2ce9c93eac qede: Ingress tc flower offload (drop action) support.
The main motive of this patch is to lay down driver's
tc offload infrastructure in place.

With these changes tc can offload various supported flow
profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop
action. Dropped flows statistic is a global counter for
all the offloaded flows for drop action and is populated
in ethtool statistics as common "gft_filter_drop".

Examples -

tc qdisc add dev p4p1 ingress
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
	skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
	skip_sw ip_proto udp src_ip 192.168.40.100 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
	skip_sw ip_proto tcp src_ip 192.168.40.100 dst_ip 192.168.40.200 \

Russell King 624c0f0239 phylink: add helper for configuring 2500BaseX modes
Add a helper for MAC drivers to use in their validate callback to deal
with 2500BaseX vs 1000BaseX modes, where the hardware supports both
but it is not possible to automatically select between them.

This helper defaults to 1000BaseX, as that is the 802.3 standard, and
will allow users to select 2500BaseX either by forcing the speed if
AN is disabled, or by changing the advertising mask if AN is enabled.
Disabling AN is not recommended as it is only the speed that we're
interested in controlling, not the duplex or pause mode parameters.

Petr Machata 88cc318ebd mlxsw: spectrum: Expose counter for all 16 TCs
Before MC-aware mode was enabled in commit 7b81953066 ("mlxsw:
spectrum: Configure MC-aware mode on mlxsw ports"), only 8 traffic
classes were used. Under MC-aware regime, however, besides using TCs
0-7 for UC traffic, it additionally uses TCs 8-15 for BUM traffic. It
is therefore desirable to show counters for these TCs as well.

Update ethtool stats pool length, mlxsw_sp_port_get_strings() and
mlxsw_sp_port_get_stats() to include artifacts for all 16 TCs. For
consistency and simplicity, expose tc_no_buffer_discard_uc_tc for BUM
TCs as well, even though it ought to stay at 0 all the time.

Petr Machata 9897dce2e3 mlxsw: spectrum: Include RFC-2819 counters in stats length
The function mlxsw_sp_port_get_sset_count() is supposed to return the
total number of ethtool strings that mlxsw supports. Specifically for
names of statistic counters (the only string type that mlxsw supports
as of now), that number is stored in MLXSW_SP_PORT_ETHTOOL_STATS_LEN.
However, when adding RFC-2891 counters, that define wasn't updated to
include the new counters. As a result, ethtool snips out the counters
towards the end of the list, which contains per-TC counters, and only
the first three traffic classes end up being reported.

Fix by adding MLXSW_SP_PORT_HW_RFC_2819_STATS_LEN as appropriate.

Before this capability the FW reported the EQ number in "log_max_eqs",
the reported value also contained FW reserved EQs, but the driver might
be failing to load on 320 cpus systems due to the fact that FW
reserved EQs were not available to the driver.

Now the driver has to obtain max_num_eqs value from new FW to get real
number of EQs available.

Zhao Chen 9c2956d2ad net-next: hinic: fix a problem in free_tx_poll()
This patch fixes the problem below. The problem can be reproduced by the
following steps:
1) Connecting all HiNIC interfaces
2) On server side
    # sudo ifconfig eth0 192.168.100.1 up #Using MLX CX4 card
    # iperf -s
3) On client side
    # sudo ifconfig eth0 192.168.100.2 up #Using our HiNIC card
    # iperf -c 192.168.101.1 -P 10 -t 100000

after hours of testing, we will see errors:

    hinic 0000:05:00.0: No MGMT msg handler, mod = 0
    hinic 0000:05:00.0: No MGMT msg handler, mod = 0
    hinic 0000:05:00.0: No MGMT msg handler, mod = 0
    hinic 0000:05:00.0: No MGMT msg handler, mod = 0

The errors are caused by the following problem.
1) The hinic_get_wqe() checks the "wq->delta" to allocate new WQEs:

	if (atomic_sub_return(num_wqebbs, &wq->delta) <= 0) {
		atomic_add(num_wqebbs, &wq->delta);
		return ERR_PTR(-EBUSY);
	}

If the WQE occupies multiple pages, the shadow WQE will be used. Then the
hinic_xmit_frame() fills the WQE.

2) While in parallel with 1), the free_tx_poll() checks the "wq->delta"
to free old WQEs:

	if ((atomic_read(&wq->delta) + num_wqebbs) > wq->q_depth)
		return ERR_PTR(-EBUSY);

There is a probability that the shadow WQE which hinic_xmit_frame() is
using will be damaged by copy_wqe_to_shadow():

	if (curr_pg != end_pg) {
		void *shadow_addr = &wq->shadow_wqe[curr_pg * wq->max_wqe_size];

		copy_wqe_to_shadow(wq, shadow_addr, num_wqebbs, *cons_idx);
		return shadow_addr;
	}

This can cause WQE data error and you will see the above error messages.
This patch fixes the problem.

David S. Miller 7116983174 Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2018-08-07

This series contains updates to i40e and i40evf only.

Sergey cleans up a duplicate call to i40e_prep_for_reset() during
shutdown.

YueHaibing cleans up i40evf by removing code that was never being used
or called within the driver.

Jake updates the ethtool statistics to use a helper function since many
of the statistics use the same basic logic for copying strings into the
supplied buffer.  Cleaned up the use of a local variable that is no
longer needed or used.  Fixed additional stats issues, including the
failure to update the data pointer which was causing stats to be
reported incorrectly.

Mariusz fixes a bug where there was an oversight in configuring FEC when
link settings were forced which was causing 25G link to be configured
incorrectly.

Piotr adds a missing return code for when the firmware returns a busy
state.  Also added the process to command firmware to start
rearrangement when switching between old NVM structure to the new flat
NVM.

Denis Bolotin 61be82b087 qed: Add Multi-TC RoCE support
RoCE qps use a pair of physical queues (pq) received from the Queue Manager
(QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block
creates a pq for each TC, and allows RoCE qps to ask for a pq with a
specific TC. As a result, qps with different VLAN priorities can be mapped
to different TCs, and employ features such as PFC and ETS.

All control commands (soft commands) goes through only Queue 0
(control and data queue). So only queue-0 needs post_lock,
other queues are only data queues and does not need post_lock

Added a flag to indicate the queue can be used for soft commands.

If this flag is set, post_lock must be acquired before posting
a command to the queue.
If this flag is clear, post_lock is invalid for the queue.
