%description
This package provides a user-space daemon which replaces the STP handling that
is built into the Linux kernel Ethernet bridge and adds support for RSTP and
PVST+.

This daemon also supports participating in MSTP.  However, due to the way the
Linux kernel implements its FIBs, it is not currently possible to map MSTP
topologies onto Linux bridges.  Therefore, mstpd will not actually block ports
on Linux bridges when MSTP is used.

# To automatically configure mstpd at boot in RHEL/Fedora:
# * If you are bridging VLANs / trunk ports, see
#   /usr/share/doc/mstpd/README.VLANs
# * Create a standard /etc/sysconfig/network-scripts/ifcfg-... file for the
#   bridge.  For example:
#   DEVICE=...
#   ONBOOT=yes
#   NM_CONTROLLED=no
#   BOOTPROTO=static
#   NOZEROCONF=yes
#   IPADDR=...
#   NETMASK=...
#   GATEWAY=...
#   IPV6INIT=yes
#   IPV6_AUTOCONF=no
#   IPV6ADDR=...
#   IPV6_DEFAULTGW=...
# * Note that TYPE=Bridge and the additional ifcfg-ethX files for each interface
#   attached to the bridge (as described at the following link) are unnecessary
#   when using mstpd.  If VLANs are not created on top of the bridge, these may
#   be present if desired, but they will simply cause the ifup-eth script to do
#   unnecessary work.  If VLANs are created on top of the bridge, TYPE=Bridge
#   must not be used, as it will cause the VLANs to be brought up before the
#   bridge, which will fail.
#   https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-networkscripts-interfaces_network-bridge.html
# * Add the following line (uncommented) at the end of the bridge's ifcfg file:
#   [ "\$0" = '/etc/sysconfig/network-scripts/ifup-eth' ] && /lib/mstpctl-utils/mstp_config_bridge "\$DEVICE"
# * Replace "br0" in the "iface" line below with the bridge's DEVICE name, and
#   adjust the mstpctl_* configuration options as needed.
#   See `man mstpctl-utils-interfaces` for documentation on the options.
#   To configure multiple bridges, add an additional "iface" line and associated
#   configuration options for each additional bridge.
