6a426d733e devtools: reduce ABI checks and static binaries
When testing compilation and checking ABI compatibility,
there is no real need of static binaries eating disks.

The static linkage of applications was already well tested,
though the static examples tested with meson were limited to "l3fwd" only.
The static build test with make is limited to "helloworld" example.

The ABI compatibility is checked on shared libraries,
and there is no need to test again on similar builds.
A new parameter is added to the function "build",
so the ABI check is enabled only for native gcc and clang shared builds,
32-bit, generic armv8 and ppc cross compilations.
In other words, it is disabled for some static builds and some Arm ones.

de6aede17b service: propagate init error in EAL
Currently, when rte_service_init() fails at initialization, the
application always gets a ENOEXEC error code. For example, with testpmd,
this is displayed as:

  Cannot init EAL: Exec format error

This error code does not describe the real issue. Instead, use the error

a86cb7e259 bus/dpaa: optimize device name parsing
Device name parsing is done on all buses during device iterations at
either EAL or ethdev levels.

When a bus implements device name parsing slowly, all iterations are
impacted. Efficient implementation is important.

The DPAA bus device name parsing has two issues: it allocates dynamic
memory and uses snprintf without a real need for it. Both can be
avoided, which improves the parsing performance.

The function is also simpler and shorter.

324242fb51 ip_frag: remove padding length of fragment
In some situations, we would get several ip fragments, which total
data length is less than min_ip_len(64) and padding with zeros.
We simulated intermediate fragments by modifying the MTU.
To illustrate the problem, we simplify the packet format and
ignore the impact of the packet header.In namespace2,
a packet whose data length is 1520 is sent.
When the packet passes tap2, the packet is divided into two
fragments: fragment A and B, similar to (1520 = 1510 + 10).
When the packet passes tap3, the larger fragment packet A is
divided into two fragments A1 and A2, similar to (1510 = 1500 + 10).
Finally, the bond interface receives three fragments:
A1, A2, and B (1520 = 1500 + 10 + 10).
One fragmented packet A2 is smaller than the minimum Ethernet
frame length, so it needs to be padded.

|---------------------------------------------------|

|--------------------------------------|mtu=1500|---|
                                       |--------|

When processing the preceding packets above,
DPDK would aggregate fragmented packets A2 and B.
And error packets are generated, which padding(zero)
is displayed in the middle of the packet.

A2 + B:
0000   fa 16 3e 9f fb 82 fa 47 b2 57 dc 20 08 00 45 00
0010   00 33 b4 66 00 ba 3f 01 c1 a5 01 01 01 01 02 01
0020   01 02 c0 c1 c2 c3 c4 c5 c6 c7 00 00 00 00 00 00
0030   00 00 00 00 00 00 00 00 00 00 00 00 c8 c9 ca cb
0040   cc cd ce cf d0 d1 d2 d3 d4 d5 d6 d7 d8 d9 da db
0050   dc dd de df e0 e1 e2 e3 e4 e5 e6

So, we would calculate the length of padding, and remove
the padding in pkt_len and data_len before aggregation.
And also we have the fix for both ipv4 and ipv6.

On Tx, lastseg->next is not being reset to null for multi segmented
packet and same mbuf can be used on Rx which has a stale mbuf entry into
mbuf->next.

On Rx, application receives mbuf with mbuf->next uninitialized though
mbuf->nb_segs is correct. Application iterates over all segments using
mbuf->next ignoring mbuf->nb_segs which leads to undefined behavior.

So earlier assumption of just having right value in mbuf->nb_segs is
enough, is incorrect. Mbuf must contain valid and synced value in
nb_segs and next pointer.

6f5f3b9982 net/bnxt: check chip reset in stop and close
While the error recovery thread is running, an application
can invoke dev_stop or dev_close_op thus triggering a race
and unwanted consequences if dev_close is invoked while the
recovery is not yet completed.
Fix by having another lock to synchronize between the 2 threads and
return EGAIN if adapter is in the middle of recovery when dev_stop
or dev_close ops are invoked

c9ffd6f886 net/bnxt: fix lock init and destroy
Invoking init/uninit locks in init_resources and uninit_resources
would end up initializing and destroying locks on every port start
stop which is not desired.
Move the 2 routines to dev_init and dev_close respectively as
locks need to be initialized and destroyed only once during the
lifetime of the driver.

899f061307 net/bnxt: add Rx logic for 58818 chips
1. On the new 58818 chips, the RX completion is largely the same except
   for the new completion opcode and the stripped VLAN format and
   checksum status. Added bnxt_parse_csum_v2(), bnxt_parse_pkt_type_v2()
   and bnxt_rx_vlan_v2() to support the new RX completion logic.
2. Disable vector mode RX/TX for 58818 chips for now.
3. The cfa_code format on 58818 chips is different than legacy chips.
   So skip cfa_code parsing logic on 58818 chips for now.

eb6ed2a99f net/bnxt: modify context memory allocation
Newer devices like SR2 may have chip backing store and do not require
host backed memory allocation.

In these cases, HWRM_FUNC_BACKING_STORE_QCAPS will return a zero entry
size to indicate contexts for which the host should not allocate backing
store.

Selectively allocate context memory based on device capabilities and
only enable backing store for the appropriate contexts

Modify VNIC accounting when enabling RFS on newer chips.
Unlike legacy chips, newer chips don't need additional VNIC resources
for ntuple filter. Fix the code accordingly so that we don't reserve
and allocate additional VNICs on newer chips.

e97661757d net/bnxt: add new Rx checksum mode
The 58818 chips support two different checksum modes.
Host driver has to register with FW which checksum mode it
prefers to use. DPDK driver want to use "cs_all_ok_mode=1".
FW advertises the support of the different checksum modes
on per VNIC basis in the HWRM_VNIC_QCAPS response.
Driver should use HWRM_VNIC_CFG to configure the needed
checksum mode.

ecf1474a61 net/bnxt: support 58818 chip family
The new chip (Stingray 2) is part of the P5 chip family with a number
of changes:

1. Implement the epoch doorbell bit for 58818 chip. With the new
   doorbell infrastructure and the unbounded index logic, now set the
   epoch doorbell bit to support proper doorbell operation on the new
   chip.  Toggle epoch bit of all rings when it's wrapped to support
   doorbell overflow checking.
2. Get the legacy doorbell size from firmware. Legacy doorbell support
   has been removed in Stingray 2. So, the fast path doorbell pages
   start from the base of the BAR. Drivers need to use
   legacy_l2_db_space_size_kb field in the hwrm_func_qcfg_output
   response to get the legacy doorbell page offset from the BAR.
3. Set VALID doorbell bit on 58818 chip family. This class of chip has a
   valid doorbell bit added and it needs to be set.
4. Use "chip_num" returned by firmware. The "chip_num" field in the
   HWRM_VER_GET output returns the chip number. Use this value to
   identify chip category for 58818 chip family.
5. Added device ids for Stingray2 PF/VF devices.
