Environment
===========
DPDK version: 9fe9c0b231c8da5435bfccb1963121b4277f961c version: dpdk25.07-rc3
OS: Fedora42/6.14.5-300.fc42.x86_64
Compiler: gcc version 15.2.1 20250808
Hardware platform: Intel(R) Xeon(R) Gold 6252N CPU @ 2.30GHz
NIC hardware: Intel Corporation Ethernet Controller X710 for 10GbE SFP+ (rev
01)

Test Setup
Steps to reproduce
==================
1.Build dpdk and examples=ip_reassembly
CC=gcc meson -Denable_kmods=False -Dlibdir=lib -Dexamples=ip_reassembly --default-library=static x86_64-native-linuxapp-gcc -Dmax_lcores=160 ninja -C x86_64-native-linuxapp-gcc

2.Start dpdk-ip_reassembly
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:31:00.0 0000:31:00.1 ./x86_64-native-linuxapp-gcc/examples/dpdk-ip_reassembly -l 1 -n 4 -a 0000:31:00.0 -a 0000:31:00.1 --file-prefix=dpdk_513316_20250910130931
--force-max-simd-bitwidth=64 -- -p 0x1 --maxflows=1024 --flowttl=3s

ethdev: reject conflicting Tx offload configurations

When an ethdev port is configured for fast mbuf release, the driver can use a Tx burst function relying on the fast mbuf release preconditions. Thus, also configuring this port or a queue on the port for transmitting segmented packets is prohibited.
Checks for these conflicting configurations have been added to the ethdev library, so the drivers don't have to implement them.
