Re: [Devel] [PATCH hci-8.1 4/8] ms/mptcp: let the retrans scheduler do its job

[no-reply@sashiko.virtuozzo.com]

> From: Paolo Abeni <pabeni@redhat.com>
> 
> Currently the MPTCP core enforces that when MPTCP-level retrans timer
> fires, at most a single dfrag is retransmitted. In some corner-cases, it
> may be necessary to retransmit multiple dfrags, and the MPTCP socket
> will need to wait multiple retrans timeout to accomplish that.
> 
> Remove the mentioned constraint, allowing to transmit multiple dfrags
> per retrans period, as long as the scheduler keeps selecting subflows
> for retransmissions and pending data is available in the rtx queue.
> The default scheduler will transmit a dfrag per available subflow.
