Subject: bnx2x: ethtool now returns unknown speed/duplex
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=382984618e847ad4621d7ccbd48f5ec702c6a78e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bnx2x: ethtool now returns unknown speed/duplex

Previously, unless both interface and link were up, ethtool returned
the requested speed/duplex when asked for the interface's settings.
This change will now enable the driver to answer correctly (i.e.,
return unknown as its answer).
