Subject: e1000e: add Tx timeout factor for 100Mbps
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4c86e0b9455c8fa8122fc2d10935e892838c8568;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

e1000e: add Tx timeout factor for 100Mbps

On some devices (e.g. 82578) not having a Tx timeout factor when linked at
100Mbps can cause false reports of hardware hangs on busy hubs.
