[AceLan Kao]

BugLink: https://bugs.launchpad.net/bugs/1788567

[Impact]
On Dell XPS 13 with Dell TB16 docking station, sometimes the devices on
docking station do not show up or takes couple minutes to be recognized.

[Fix]
This issue doesn't exist in 4.16 vanilla kernel, and after bisected the
kernel and found below commit fixes this issue.
   cc5db3150e87 net: qcom/emac: Use proper free methods during TX
Applied this commit on top of Bionic 4.15 kernel and confirmed it works.

[Regression Potential]
Low, this commit is more like a patch fixes a bug which has been
introduced since the driver was created. It aligns the dma_map and
dma_unmap methods which might cause issues in some cases.
