focal ,mlx5, steering, Add support for non FDB domain

[Amir Tzin]

[Impact]
Although focal kernel supports non FDB domains, rdma-core support is missing.
we need the below rdma-core patches to add this support

[Test Case]
install latest DPDK from github
$ git clone git://dpdk.org/dpdk
$ cd <dpdk download folder>
$ mason build
$ ninja -C build

- Run testpmd

/download/dpdk/build-meson/app/dpdk-testpmd -n 4 -a 0000:00:06.0,l3_vxlan_en=1,dv_flow_en=1 -a 0000:00:07.0,l3_vxlan_en=1,dv_flow_en=1 -- --mbcache=512 -i --nb-cores=11 --txd=256 --rxd=256 --burst=64 --mask-event=intr_lsc --mask-event=flow_aged --vxlan-gpe-port=6081

- Try to create any SW Steering rule "group > 0 "

[Regression Potential]
regression potential is low since we are adding a new capability to support rx/tx domains without touching/changing behaviour of any existing functionality.

[Other Info]

Feature patchset:
userspace (rdma-core-31):
6724f653 mlx5: DR, Query RoCE capabilities
244015c4 mlx5: DR, Enable SW Steering RX/TX domains

both patches cleanly applied on debian/28.1 branch
