@acelan, I'm unsure on where this patch first came from and also don't understand the impact from calling this. I know it was discussed on some forums as a solution to performance problems. The reason that the vendor hasn't submitted upstream is they said there was discussion that this should be fixed in TCP driver and it's cross vendor impact. I don't think that is true because this is not seen on Intel, only on QCA.
Given that and assuming it still has the large performance improvement on newer kernel I think it's worth an attempt to submit upstream along with the test data. The data is irrefutable and if the maintainers think it would be better to put the patch somewhere else, they can recommend where it should go. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1692836 Title: Dell XPS 9360 wifi 5G performance is poor Status in HWE Next: Fix Committed Status in HWE Next xenial series: Fix Committed Status in linux package in Ubuntu: Fix Committed Bug description: TX throughput is not good in Ubuntu in IEEE 802.11ac mode. Measured Rx 60Mbit/s and Tx 12Mbit/s with Ubuntu Windows 10 (1607) performs much better with on transmit side Rx 73MBit/s and Tx 62MBit/s using the same hardware setup. Same result with WPA2 disabled in unencrypted mode.
