+====== Persisting Network Hardware Settings ======
+When installing ''ethtool'' on Debian, a script is placed at ''/etc/network/if-up.d/ethtool'' that, once an interface is brought up, runs through all the settings for all interfaces and makes changes to the hardware driver via ''ethtool''.
+The proper way to persist settings in Debian, for instance, to enable checksum offloading, is to make the settings in the interfaces file but without using an ''up'' or ''post-up'' script.
+For instance, the following settings will bring up the interface ''eth0'' via DHCP and then enable TSO on the interface:
+<code>
+auto eth0
+iface eth0 inet dhcp
+    offload-tx on
+    offload-sg on
+    offload-tso on
+</code>
