Interface LinkSetXdpObjectOptions

Attaches a XDP/BPF program to the given device.

The FILE points to a BPF ELF file (f.e. generated by LLVM) that contains the BPF program code, map specifications, etc. If a XDP/BPF program is already attached to the given device, an error will be thrown.

If no XDP/BPF program is currently attached, the device supports XDP and the program from the BPF ELF file passes the kernel verifier, then it will be attached to the device.

If the option -force is passed to ip then any prior attached XDP/BPF program will be atomically overridden and no error will be thrown in this case.

If no section option is passed, then the default section name ("prog") will be assumed, otherwise the provided section name will be used.

If no verbose option is passed, then a verifier log will only be dumped on load error. See also EXAMPLES section for usage examples.

Specifies a section name that contains the BPF program code. If no section name is specified, the default one ("prog") will be used. This option is to be passed with the object option.

Act in verbose mode. For example, even in case of success, this will print the verifier log in case a program was loaded from a BPF ELF file.
