Subject: [PATCH] r8169: enable SG/TSO on selected chip versions per default
|
|
|
|
Due to problem reports in the past SG and TSO/TSO6 are disabled per
|
|
default. It's not fully clear which chip versions are affected, so we
|
|
may impact also users of unaffected chip versions, unless they know
|
|
how to use ethtool for enabling SG/TSO/TSO6.
|
|
Vendor drivers r8168/r8125 enable SG/TSO/TSO6 for selected chip
|
|
versions per default, I'd interpret this as confirmation that these
|
|
chip versions are unaffected. So let's do the same here.
