This patch simplifies the check for Tx pending traffic and makes it more
holistic as there being any difference between next_to_use and
next_to_clean is much more informative than if head and tail are equal, as
it is possible for us to either not update tail, or not be notified of
completed work in which case next_to_clean would not be equal to head.
In addition the simplification makes it so that we don't have to read
hardware which allows us to drop a number of variables that were previously
being used in the call.

This change is a fix of the macvlan offload so that we correctly handle
macvlan offloaded devices. Specifically we were configuring our limits based
on the assumption that we were going to max out the RSS indices for every
mode. As a result when we went to 15 or more macvlan interfaces we were
forced into the 2 queue RSS mode on VFs even though they could have still
supported 4.
This change splits the logic up so that we limit either the total number of
macvlan instances if DCB is enabled, or limit the number of RSS queues used
per macvlan (instead of per pool) if SR-IOV is enabled. By doing this we
can make best use of the part.
In addition I have increased the maximum number of supported interfaces to
63 with one queue per offloaded interface as this more closely reflects the
actual values supported by the interface.

The num_rx_pools value is overwritten when we reinitialize the queue
configuration. In reality we shouldn't need to be updating the value since
it is redone every time we call into ixgbe_setup_tc so for now just drop
the spots where we were incrementing or decrementing the value.

In order for RSS to work on the macvlan pools of the X550 we need to
populate the MRQC, RETA, and RSS key values for each pool. This patch makes
it so that we now take care of that.
In addition I have dropped the macvlan specific configuration of psrtype
since it is redundant with the code that already exists for configuring
this value.

If the number of VFs are changed we need to reinitialize the part since the
offset for the device and the number of pools will be incorrect. Without
this change we can end up seeing Tx hangs and dropped Rx frames for
incoming traffic.
In addition we should drop the code that is arbitrarily changing the
default pool and queue configuration. Instead we should wait until the port
is reset and reconfigured via ixgbe_sriov_reinit.

When SR-IOV was enabled the macvlan offload was configuring several filters
with the wrong pool value. This would result in the macvlan interfaces not
being able to receive traffic that had to pass over the physical interface.
To fix it wrap the pool argument in the VMDQ_P macro which will add the
necessary offset to get to the actual VMDq pool

When setting MTU, actually what we do is configuring the max frame size
for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be
considered. And the frame size which is less than the default value
should not be set to the hardware. Because in the hardware, the the max
frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.
This patch fixes the bug setting a error max frame size to hardware.

When using the MAPv4 packet format, receive checksum offload can be
enabled in hardware. The checksum computation over pseudo header is
not offloaded but the rest of the checksum computation over
the payload is offloaded. This applies only for TCP / UDP packets
which are not fragmented.
rmnet validates the TCP/UDP checksum for the packet using the checksum
from the checksum trailer added to the packet by hardware. The
validation performed is as following -
1. Perform 1's complement over the checksum value from the trailer
2. Compute 1's complement checksum over IPv4 / IPv6 header and
subtracts it from the value from step 1
3. Computes 1's complement checksum over IPv4 / IPv6 pseudo header and
adds it to the value from step 2
4. Subtracts the checksum value from the TCP / UDP header from the
value from step 3.
5. Compares the value from step 4 to the checksum value from the
TCP / UDP header.
6. If the comparison in step 5 succeeds, CHECKSUM_UNNECESSARY is set
and the packet is passed on to network stack. If there is a
failure, then the packet is passed on as such without modifying
the ip_summed field.
The checksum field is also checked for UDP checksum 0 as per RFC 768
and for unexpected TCP checksum of 0.
If checksum offload is disabled when using MAPv4 packet format in
receive path, the packet is queued as is to network stack without
the validations above.

The MAPv4 packet format adds support for RX / TX checksum offload.
For a bi-directional UDP stream at a rate of 570 / 146 Mbps, roughly
10% CPU cycles are saved.
For receive path, there is a checksum trailer appended to the end of
the MAP packet. The valid field indicates if hardware has computed
the checksum. csum_start_offset indicates the offset from the start
of the IP header from which hardware has computed checksum.
csum_length is the number of bytes over which the checksum was
computed and the resulting value is csum_value.
In the transmit path, a header is appended between the end of the MAP
header and the start of the IP packet. csum_start_offset is the offset
in bytes from which hardware will compute the checksum if the
csum_enabled bit is set. udp_ip4_ind indicates if the checksum
value of 0 is valid or not. csum_insert_offset is the offset from the
csum_start_offset where hardware will insert the computed checksum.
The use of this additional packet format for checksum offload is
explained in subsequent patches.

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-01-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add a start of a framework for extending struct xdp_buff without
having the overhead of populating every data at runtime. Idea
is to have a new per-queue struct xdp_rxq_info that holds read
mostly data (currently that is, queue number and a pointer to
the corresponding netdev) which is set up during rxqueue config
time. When a XDP program is invoked, struct xdp_buff holds a
pointer to struct xdp_rxq_info that the BPF program can then
walk. The user facing BPF program that uses struct xdp_md for
context can use these members directly, and the verifier rewrites
context access transparently by walking the xdp_rxq_info and
net_device pointers to load the data, from Jesper.
2) Redo the reporting of offload device information to user space
such that it works in combination with network namespaces. The
latter is reported through a device/inode tuple as similarly
done in other subsystems as well (e.g. perf) in order to identify
the namespace. For this to work, ns_get_path() has been generalized
such that the namespace can be retrieved not only from a specific
task (perf case), but also from a callback where we deduce the
netns (ns_common) from a netdevice. bpftool support using the new
uapi info and extensive test cases for test_offload.py in BPF
selftests have been added as well, from Jakub.
3) Add two bpftool improvements: i) properly report the bpftool
version such that it corresponds to the version from the kernel
source tree. So pick the right linux/version.h from the source
tree instead of the installed one. ii) fix bpftool and also
bpf_jit_disasm build with bintutils >= 2.9. The reason for the
build breakage is that binutils library changed the function
signature to select the disassembler. Given this is needed in
multiple tools, add a proper feature detection to the
tools/build/features infrastructure, from Roman.
4) Implement the BPF syscall command BPF_MAP_GET_NEXT_KEY for the
stacktrace map. It is currently unimplemented, but there are
use cases where user space needs to walk all stacktrace map
entries e.g. for dumping or deleting map entries w/o having to
close and recreate the map. Add BPF selftests along with it,
from Yonghong.
5) Few follow-up cleanups for the bpftool cgroup code: i) rename
the cgroup 'list' command into 'show' as we have it for other
subcommands as well, ii) then alias the 'show' command such that
'list' is accepted which is also common practice in iproute2,
and iii) remove couple of newlines from error messages using
p_err(), from Jakub.
6) Two follow-up cleanups to sockmap code: i) remove the unused
bpf_compute_data_end_sk_skb() function and ii) only build the
sockmap infrastructure when CONFIG_INET is enabled since it's
only aware of TCP sockets at this time, from John.

This driver uses a bool scheme for "enable"/"disable" when setting up
different resources. Thus, the hook points for xdp_rxq_info is done
in the same function call nicvf_rcv_queue_config(). This is activated
through enable/disable via nicvf_config_data_transfer(), which is tied
into nicvf_stop()/nicvf_open().
Extending driver packet handler call-path nicvf_rcv_pkt_handler() with
a pointer to the given struct rcv_queue, in-order to access the
xdp_rxq_info data area (in nicvf_xdp_rx()).
V2: Driver have no proper error path for failed XDP RX-queue info reg,
as nicvf_rcv_queue_config is a void function.
