Subject: [Bloat] what is the correct linux tc u32 match to ignore ecn but preserve tos?
Date: Thu, 28 Jul 2016 19:27:02 +0200 [thread overview]
Message-ID: <CAA93jw48xb7g-q839iixUadRG9GH9e_W5KvjPtpKKij=UmOJvg@mail.gmail.com> (raw)
I can't ever get my endianess straight, and I figure that someone here
might "just know"
Do I use match u8 0xfc or 0xcf?
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
match ip tos 0x10 0xff flowid 1:10
(am trying to revise this from in front of a mac:
https://www.bufferbloat.net/projects/cerowrt/wiki/Wondershaper_Must_Die/
)
Bonus points if you can come up with the right tc filter line for ipv6.
What I would probably do is have a filter chain to then classify the
thing further for L4s, but I don't understand how or where I'd direct
CE markings correctly. (?)
How does it happen in the pi2 code? is that on github somewhere?
