  Target Milestone: ---

[Environment]
DPDK version: 
a86f381b82 (HEAD -> main, tag: v24.03-rc2, origin/main, origin/HEAD) version:
24.03-rc2
Other software versions: name/version for QEMU, OVS, etc. Repeat as required.
OS: Ubuntu 22.04.3 LTS/5.15.0-92-generic
Compiler: gcc version 11.4.0
Hardware platform: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1, Build app and set randomize_va_space=0
rm -fr x86_64-native-linuxapp-gcc/
CC=gcc meson -Denable_kmods=True -Dlibdir=lib  -Dbuildtype=debug
-Db_lundef=false -Db_sanitize=address --default-library=static
x86_64-native-linuxapp-gcc
meson configure -Dexamples=dma x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

echo 0 > /proc/sys/kernel/randomize_va_space


2, Bind dma to vfio-pci
./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:00:01.0 0000:00:01.1
0000:00:01.2 0000:00:01.3

3, Launch primary app
x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -l 5-6 -n 8 -a 0000:00:01.0 -a
0000:00:01.1 -a 0000:00:01.2 -a 0000:00:01.3 
--file-prefix=dpdk_2693680_20240314155440  --vdev net_null_0
--proc-type=primary  -- -i
testpmd> port stop all

4, Launch secondary app: dpdk-dma
x86_64-native-linuxapp-gcc/examples/dpdk-dma  -l 5-7 -n 8 -a 0000:00:01.0 -a
0000:00:01.1 -a 0000:00:01.2 -a 0000:00:01.3 
--file-prefix=dpdk_2693680_20240314155440      --proc-type=secondary --vdev
net_null_0 -- -p 0x1 -q 4 --no-mac-updating -c hw

    net/bnxt: support 400G speed for P7 devices

    P7 devices report speeds over speeds2 hsi fields. Adding required
    support to capture the capability from phy_qcap and save the
    speeds2 fields into driver priv structure.
    In fixed mode update the link_speed from force_link_speeds2 field.
    Updates to logging to provide more info regarding numbers of lanes
    and the link signal mode.

    Some code refactoring done for PHY auto detect and displaying
    XCVR information.

if don't set echo 0 > /proc/sys/kernel/randomize_va_space, this error
disappears
