+
+Description
+===========
+
+**linux-ice** sets all recommended options for the Linux ice device driver.
+
+Recommended options
+===================
+
+| **Enabling disable-fw-lldp**
+| Many Intel network cards such as the X700 Series drop LLDP pakets by default.
+| When using LACP (802.1ad) this has the effect that after a reboot of one switch,
+| the bond interfaces do not recover. Disabling the firewalling of LLDP pakets on
+| the network card allows the operating system (= Linux kernel) to actually recieve
+| the pakets and re-establish the bonded connection.
+
+| **Enabling link-down-on-close**
+| Many Intel network cards such as the X700 Series do not take down the link
+| when the corresponding interface is deconfigured. This is in contrast to the
+| consumer (Intel) network cards that usually do this. Therefore, without enabling
+| the link-down-on-close, most assumptions of HA stacks (e.g. pacemaker/corosync)
+| are not met and can lead to various unwanted effects. Enabling this options
+| restores the usual behaviour.
