stack: relax pop CAS ordering
Replace the store-release by relaxed for the CAS success at the end of
pop. Release isn't needed, because there is not write to data that need
to be synchronized.
The only preceding write is when the length is decreased, but the length
CAS loop already ensures the right synchronization.
The situation to avoid is when a thread sees the old length but the new
list, that doesn't have enough items for pop to success.
But the CAS success on length before the pop loop ensures any core reads
and updates the latest length, preventing this situation.
The store-release is also used to make sure that the items are read
before the head is updated, in order to prevent a core in pop to read an
incorrect value because another core rewrites it with push.
But this isn't needed, because items are read only when removed from the
used list. Right after this, they are pushed to the free list, and the
store-release in push makes sure the items are read before they are
visible in the free list.

bus/pci: fix mapping BAR containing MSI-X table
When the BAR contains MSI-X table, pci_vfio_mmap_bar() tries to skip
the table and map the rest. "map around it" is the phrase used in the
source. The function splits the BAR into two regions: the region
before the table (first part or memreg[0]) and the region after the
table (second part or memreg[1]).
For hardware that has MSI-X vector table offset 0, the first part does
not exist (memreg[0].size == 0).
Capabilities: [60] MSI-X: Enable- Count=48 Masked-
Vector table: BAR=2 offset=
00000000
PBA: BAR=2 offset=
00001000
The mapping part of the function maps the first part, if it
exists. Then, it maps the second part, if it exists and "if mapping the
first part succeeded".
The recent change that replaces MAP_FAILED with NULL breaks the "if
mapping the first part succeeded" condition (1) in the snippet below.
void *map_addr = NULL;
if (memreg[0].size) {
/* actual map of first part */
map_addr = pci_map_resource(...);
}
/* if there's a second part, try to map it */
if (map_addr != NULL // -- (1)
&& memreg[1].offset && memreg[1].size) {
[...]
}
if (map_addr == NULL) {
RTE_LOG(ERR, EAL, "Failed to map pci BAR%d\n",
bar_index);
return -1;
}
When the first part does not exist, (1) sees map_addr is still NULL,
and the function fails. This behavior is a regression and fails
probing hardware with vector table offset 0.
Previously, (1) was "map_addr != MAP_FAILED", which meant
pci_map_resource() was actually attempted and failed. So, expand (1)
to check if the first part exists as well, to match the semantics of
MAP_FAILED.

When a VLAN pattern is present, the flow handler always copies its
inner_type to the match buffer regardless of its value (i.e. HW
matches inner_type against packet's inner ethertype). When inner_type
spec and mask are both 0, adding it to the match buffer is usually
harmless but breaks the following pattern used in some applications
like OVS-DPDK.
flow create 0 ingress ... pattern eth ... type is 0x0800 /
vlan tci spec 0x2 tci mask 0xefff / ipv4 / end actions count /
of_pop_vlan / ...
The VLAN pattern's inner_type is 0. And the outer eth pattern's type
actually specifies the inner ethertype. The outer ethertype (0x0800)
is first copied to the match buffer. Then, the driver copies
inner_type (0) to the match buffer, which overwrites the existing
0x0800 with 0 and breaks the app usage above.
Simply ignore inner_type when it is 0, which is the correct
behavior. As a byproduct, the driver can support the usage like the
above.

VF representor ports can create flows on VFs through the PF flowman

When a representor port invokes flow APIs, use the PF port's flowman

representor, use VF handle instead of PF handle.
2. Serialize flow API calls
Multiple application thread may invoke flow APIs through PF and VF

share the same PF flowman instance. Use a lock to serialize API
calls. Lock is used only when representors exist.
3. Add functions to create flows for implicit representor paths

functions below create flow rules to implement that path.
- enic_fm_add_rep2vf_flow()
- enic_fm_add_vf2rep_flow()

are not visible to application, and the flush API does not destroy
them. They are automatically deleted when the representor port stops

2. Add vnic_register_lock()
As PF and VF representors appear as independent ports to the

ethdev: support getting Rx buffer size in Rx queue info
Add a field named rx_buf_size in rte_eth_rxq_info to indicate the buffer
size used in receiving packets for HW.
In this way, upper-layer users can get this information by calling
rte_eth_rx_queue_info_get.

net/memif: relax barrier for zero copy path
Using 'rte_mb' to synchronize the shared ring head/tail between producer

Relax the expensive barrier with c11 atomic with explicit memory
ordering can improve 3.6% performance on throughput.

net/hns3: fix crash when Tx multiple buffer packets
Currently, there is a possibility that segment faults occur when sending
packets whose payloads are stored in multiple buffers based on hns3
network engine. The related core dump information as follows:
Program terminated with signal 11, Segmentation fault.
0 hns3_reassemble_tx_pkts
2512 temp = temp->next;
Missing separate debuginfos, use:
(gdb) bt

8 0x0000ffffa6f7fc48 in start_thread
9 0x0000ffffa6ed1600 in thread_start
The root cause is that hns3 PMD driver invokes the rte_pktmbuf_free_seg
API function to release the same rte_mbuf multiple times. The rte_mbuf
pointer is not set to NULL in the internal function
hns3_rx_queue_release_mbufs which is invoked during queue setup, stop
and close. As a result the rte_mbuf in Rx queues will be repeatedly
released when the user application setup queues or stop/start the dev
for multiple times.
Probably for performance reasons, DPDK mempool lib does not check for
the repeated rte_mbuf releases. The Address of released rte_mbuf are
directly stored into the per lcore cache of the mempool. This makes the
rte_mbufs obtained from mempool by calling rte_mempool_get_bulk API
function repetitively. ultimately, it causes to access to a NULL
pointer in PMD driver.
This patch fixes this problem by setting released mbuf pointer to NULL
in the internal function named hns3_rx_queue_release_mbuf. And the other
internal function named hns3_reassemble_tx_pkts is optimized to avoid a
similar problem.

net/hns3: add restriction on setting VF MTU
When Rx of scattered packets is off, we have some possibility of using
vector Rx process function or simple Rx functions in hns3 PMD driver.
If the input MTU is increased and the maximum length of received packets
is greater than the length of a buffer for Rx packets, the hardware
network engine needs to use multiple BDs and buffers to store these
packets. This will cause problems when still using vector Rx process
function or simple Rx function to receiving packets. So, when Rx of
scattered packets is off and device is started, it is not permitted to
increase MTU so that the maximum length of Rx packets is greater than Rx
buffer length.
