Title:
Poor kernel builtin r8169 driver performance, r8168-dkms driver not
compatible with kernels > 4.7
Status in linux package in Ubuntu:
Confirmed
Status in r8168-dkms package in Ubuntu:
New
Bug description:
From the Bionic archive (universe) the r8168-dkms driver is supposed
to get better performance compared to the kernel builin r8169 one,
which has degraded speed mainly due to MTU 576 and only using 100
Mbits/s.
Installing that driver onto a 4.13.13 based kernel goes as expected,
but after rebooting there is no network at all, ping fails.
Blacklisting r8169 or not makes no difference.
An issue is opened on https://github.com/mtorromeo/r8168/issues/9
So that driver is not usable actually with the proposed kernels from
the recent ubuntu releases; maybe the driver description could point
that limitation, if a bypass is not found.
About the kernel itself, maybe the builtin r8169 driver could deliver better
performance , for example setting MTU to >=1492 at least.
