STP is important for detecting loops in the ethernet traffic and
blocking ports. The linux software bridge will want to see these
packets.
IGMP will become important when you implement multicast support in the
switch. It will allow you to optimize the distribution of multicast to
only ports which have expressed an interest in receiving the group.
Currently we don't have any switch driver making use of 802.1x. It is
something which many switches have, but so far nobody has spent the
time to implement an interface to wpa_supplicant etc.
