setting recommended options for the Linux ice device driver

Synopsis
========

| **linux-ice** start|stop|status

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.
