2017-10-22	tools: bpftool: add `bpftool prog help` as real command i.r.t exit code	Quentin Monnet	1	-0/+1
	Make error messages and return codes more consistent. Specifically, make `bpftool prog help` a real command, instead of printing usage by default for a non-recognized "help" command. Output is the same, but this makes bpftool return with a success value instead of an error.

2017-10-22	tools: bpftool: use err() instead of info() if there are too many insns	Quentin Monnet	1	-1/+1
	Make error messages and return codes more consistent. Specifically, replace the use of info() macro with err() when too many eBPF instructions are received to be dumped, given that bpftool returns with a non-null exit value in that case.

2017-10-22	tools: bpftool: fix return value when all eBPF programs have been shown	Quentin Monnet	1	-1/+3
	Change the program to have a more consistent return code. Specifically, do not make bpftool return an error code simply because it reaches the end of the list of the eBPF programs to show.

2017-10-22	tools: bpftool: add pointer to file argument to print_hex()	Quentin Monnet	1	-2/+2
	Make print_hex() able to print to any file instead of standard output only, and rename it to fprint_hex(). The function can now be called with the info() macro, for example, without splitting the output between standard and error outputs.

2017-10-18	tools: bpftool: use more common tag format	Jakub Kicinski	1	-1/+1
	Program tag is usually displayed as string of bytes without any separators (e.g. as "aa5520b1090cfeb6" vs MAC addr-like format bpftool uses currently: "aa:55:20:b1:09:0c:fe:b6"). Make bptfool use the more common format both for displaying the tag and selecting the program by tag. This was pointed out in review but I misunderstood the comment.

	Compile the instruction printer from kernel/bpf and use it for disassembling "translated" eBPF code.
