Yes it looks like it was refactored as a result of f2f6ecabe, but
following the refactor here is where it would go in a newer kernel.

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.
Steps to Reproduce:
1. connect to Wifi
2. copy a large file from XPS 13 to a share on a 2nd system
