Subject: [PATCH bpf-next 6/6] bpftool: Fix mixed indentation in documentation
Some paragraphs in bpftool's documentation have a mix of tabs and spaces
for indentation. Let's make it consistent.
This patch brings no change to the text content.

DESCRIPTION

**bpftool net { show | list }** [ **dev** *NAME* ]
- List bpf program attachments in the kernel networking subsystem.
+ List bpf program attachments in the kernel networking subsystem.
- Currently, only device driver xdp attachments and tc filter
- classification/action attachments are implemented, i.e., for
- program types **BPF_PROG_TYPE_SCHED_CLS**,
- **BPF_PROG_TYPE_SCHED_ACT** and **BPF_PROG_TYPE_XDP**.
- For programs attached to a particular cgroup, e.g.,
- **BPF_PROG_TYPE_CGROUP_SKB**, **BPF_PROG_TYPE_CGROUP_SOCK**,
- **BPF_PROG_TYPE_SOCK_OPS** and **BPF_PROG_TYPE_CGROUP_SOCK_ADDR**,
- users can use **bpftool cgroup** to dump cgroup attachments.
- For sk_{filter, skb, msg, reuseport} and lwt/seg6
- bpf programs, users should consult other tools, e.g., iproute2.

- The current output will start with all xdp program attachments, followed by
- all tc class/qdisc bpf program attachments. Both xdp programs and
- tc programs are ordered based on ifindex number. If multiple bpf
- programs attached to the same networking device through **tc filter**,
- the order will be first all bpf programs attached to tc classes, then
- all bpf programs attached to non clsact qdiscs, and finally all
- bpf programs attached to root and clsact qdisc.

**bpftool** **net attach** *ATTACH_TYPE* *PROG* **dev** *NAME* [ **overwrite** ]
- Attach bpf program *PROG* to network interface *NAME* with
- type specified by *ATTACH_TYPE*. Previously attached bpf program
- can be replaced by the command used with **overwrite** option.
- Currently, only XDP-related modes are supported for *ATTACH_TYPE*.

- *ATTACH_TYPE* can be of:
- **xdp** - try native XDP and fallback to generic XDP if NIC driver does not support it;
- **xdpgeneric** - Generic XDP. runs at generic XDP hook when packet already enters receive path as skb;
- **xdpdrv** - Native XDP. runs earliest point in driver's receive path;
- **xdpoffload** - Offload XDP. runs directly on NIC on each packet reception;

- *ATTACH_TYPE* previously used for attach must be specified.
