Re: [Devel] [PATCH hci-8.1 6/8] ms/mptcp: implemented OoO queue pruning

[no-reply@sashiko.virtuozzo.com]

> From: Paolo Abeni <pabeni@redhat.com>

> When moving incoming skbs in the msk receive queue and the latter

> at the subflow level. The main difference relies in the stop condition:
> since MPTCP does not perform collapsing, it's better off dropping the
> bare minimum to fit the (newer) incoming packet.
