Subject: ixgbe: feature - driver to default with FC on.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd7664f69fe1f3f75b664503ae3e11a2971a4865;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ixgbe: feature - driver to default with FC on.

In the past flow control wasn't enabled by default under the
incorrect assumption that this opened up us to a denial of
service attack.  However since any switch that forwarded flow
control would be extremely msiconfigured and/or buggy, this
concern no longer out weighs the preformance gains from
having FC enabled.
