The current architecture detection method in bpftool is designed for host case. For offload case, we can't use the architecture of "bpftool" itself. Instead, we could call the existing "ifindex_to_name_ns" to get DEVNAME, then read pci id from /sys/class/dev/DEVNAME/device/vendor, finally we map vendor id to bfd arch name which will finally be used to select bfd backend for the disassembler.
