our report is based on bisect results. so the 20.1% regression is the data from
5628f3fe3b comparing to its parent commit:
844c9db7f7 ("net: use llist for sd->defer_list")

844c9db7f7 is good base. 5628f3fe3b introduces regression in our tests.

when we finish the bisect, we also tested the tip of mainline at that time
[still regression on linus/master cb015814f8b6eebcbb8e46e111d108892c5e6821]
this commit has the similar data to 5628f3fe3b, so it seems neither
e20dfbad8aab2 or 21664814b89e introduces further regression.
