Subject: [RFC net-next] llc: jumbo frame support
Date: Mon, 13 Jul 2026 14:43:37 +0200 [thread overview]
Message-ID: <20260713124545.462790-1-equinox@diac24.net> (raw)
Hi all,
this is a somewhat random stab at 802.1AC / jumbo frame support for LLC.
It kinda fell out as a side effect from poking at FRRouting's IS-IS
socket use. Unfortunately even if this gets picked up right now, it'll
be quite a bit of time before we can even consider using it there. (And
it's not clear that it'll go that way.)
Regardless, it's a tiny change & my messing around with things
effectively got me the selftest too.
The fact that AF_LLC can't be used in a network namespace is a bit of a
problem though (haven't looked at how much work that would be, unlike
the jumbo frame support this didn't fall out "for free"), and so is the
fact that AF_LLC is on limited maintenance...
It's an RFC. Comments appreciated.
Cheers,
equi (David)
