V2 should address the comments highlighted in the review: the implementation is The patches have been tested mainly against an MDM9207 based modem through USB Not sure if I got their advice right, but this patchset add also generic ethtool Moreover, Greg and Jakub suggested also to use ethtool for the configuration: See the discussion at it turned out that rmnet was a better candidate for the implementation. The first attempt to solve this issue was in qmi_wwan qmap implementation,

SDX20), or at least itĭoes not happen at the throughputs I'm able to test currently: maybe the sameĬould happen when moving close to the maximum rates supported by those modems.Īnyway, having the tx aggregation enabled should not hurt.

This issue does not happen with high-cat modems (e.g. The same scenario with tx aggregation enabled is pictured at Tx and rx flows, tx throughput has an huge drop. In tx and minor issues in rx (not able to reach max throughput). Testing with iperf TCP, when rx and tx flows are tested singularly there's no issue What is actually happening is pictured at I verified this problem with rmnet + qmi_wwan by using a MDM9207 Cat.

Some low-cat Thread-x based modems are not capable of properly reaching the maximumĪllowed throughput both in tx and rx during a bidirectional test if tx packets This patchset implements tx qmap packets aggregation in rmnet and generic Subash Abhinov Kasiviswanathan, Sean Tranchetti, Jonathan Corbet,Ĭc: Bjørn Mork, Greg Kroah-Hartman, netdev, Daniele Palmas To: David Miller, Jakub Kicinski, Paolo Abeni, Eric Dumazet,
