suricata.yaml: Start moving to IPFire specific configuration

Browse Source 
Remove a lot of stuff and options which are deactivated during compiling,
unsupported by the plattform or not used in IPFire.

Add an advice to the full documented suricata-example.yaml file which also
is shipped by IPFire.

More work needs to be done.

See #11808

#
# In normal mode a pcap file "filename" is created in the default-log-dir,
# or are as specified by "dir".
# In multi mode, a file is created per thread. This will perform much
# better, but will create multiple files where 'normal' would create one.
# In multi mode the filename takes a few special variables:
# - %n -- thread number
# - %i -- thread id
# - %t -- timestamp (secs or secs.usecs based on 'ts-format'
# E.g. filename: pcap.%n.%t
#
# Note that it's possible to use directories, but the directories are not
# created by Suricata. E.g. filename: pcaps/%n/log.%s will log into the
# per thread directory.

# is: 8*1000*2000 ~ 16TiB.

# If you want packet to be sent to another queue after an ACCEPT decision
# set mode to 'route' and set next-queue value.

# To reach maximum throughput disable all receive-, segmentation-,

# Disabling Tx checksum offloading is *required* for connecting OS endpoint

# You can use the following variables to activate netmap tap or IPS mode.
# If copy-mode is set to ips or tap, the traffic coming to the current
# interface will be copied to the copy-iface interface. If 'tap' is set, the
# copy is complete. If 'ips' is set, the packet matching a 'drop' action
# will not be copied.
# To specify the OS as the copy-iface (so the OS can route packets, or forward
# to a service running on the same machine) add a plus sign at the end
# (e.g. "copy-iface: eth0+"). Don't forget to set up a symmetrical eth0+ -> eth0
# for return packets. Hardware checksumming must be *off* on the interface if
# using an OS endpoint (e.g. 'ifconfig eth0 -rxcsum -txcsum -rxcsum6 -txcsum6' for FreeBSD
# or 'ethtool -K eth0 tx off rx off' for Linux).

# For FreeBSD ipfw(8) divert(4) support.
# Please make sure you have ipfw_load="YES" and ipdivert_load="YES"
# in /etc/loader.conf or kldload'ing the appropriate kernel modules.
# Additionally, you need to have an ipfw rule for the engine to see
# the packets from ipfw. For Example:
#
# ipfw add 100 divert 8000 ip from any to any
#
# The 8000 above should be the same number you passed on the command
# line, i.e. -d 8000
#
ipfw:
# Reinject packets at the specified ipfw rule number. This config
# option is the ipfw rule number AT WHICH rule processing continues
# in the ipfw processing system after the engine has finished
# inspecting the packet for acceptance. If no rule number is specified,
# accepted packets are reinjected at the divert rule which they entered
# and IPFW rule processing continues. No check is done to verify
# this will rule makes sense so care must be taken to avoid loops in ipfw.
#
## The following example tells the engine to reinject packets
# back into the ipfw firewall AT rule number 5500:
#
# ipfw-reinjection-rule-number: 5500
