From 2dc7c1fef9565c73c5054fd3c134afada09476c1 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 16 Oct 2017 10:12:54 -0700 Subject: [PATCH] tools: bpftool: use more common tag format 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.
