*	Remove extra semicolons.	Andrew Thompson	2008-03-17	1	-2/+2
\| \| \| \| \| \| \|	Pointed out by: antoine Notes: svn path=/head/; revision=177289
*	Switch the LACP state machine over to its own mutex to protect the internals,	Andrew Thompson	2008-03-16	1	-3/+47
\| \| \| \| \| \| \| \| \| \|	this means that it no longer grabs the lagg rwlock. Use two port table arrays which list the active ports for Tx and switch between them with an atomic op. Now the lagg rwlock is only exclusively locked for management (ioctls) and queuing of lacp control frames isnt needed. Notes: svn path=/head/; revision=177274
*	Pass any unmatched slowprotocols frames up the stack instead of dropping them,	Andrew Thompson	2007-12-31	1	-1/+1
\| \| \| \| \| \| \|	there are more subtypes than just LACP. Notes: svn path=/head/; revision=175005

*	non-functional cleanup	Andrew Thompson	2007-06-12	1	-16/+6

*	Compare the partner system priority when choosing the aggregator.	Andrew Thompson	2007-05-19	1	-0/+2
\| \| \| \|	Notes: svn path=/head/; revision=169741
*	Implement the Marker Protocol. A marker frame is placed on the interface queue	Andrew Thompson	2007-05-19	1	-24/+28
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	of each port and any further packets are blocked, when the all the marker frames have been returned to us from the remote network device then we can be sure that all interface queues are empty. This is needed when a port is added or removed from the aggregation since it will affect the hash based distribution, if the queues are not empty then a packet from an existing connection may be placed on a different interface and arrive out of order. This was previously achieved by suppressing transmission for 1 second, now that there is an active feedback this timeout as been increased to 3 seconds and used as a fallback.

*	Change from a mutex to a read/write lock. This allows the tx port to be	Andrew Thompson	2007-05-15	1	-2/+3

*	Change from using if_delmulti() to if_delmulti_ifma() as it simplifies the code	Andrew Thompson	2007-05-07	1	-0/+1

*	Rename the trunk(4) driver to lagg(4) as it is too similar to vlan trunking.	Andrew Thompson	2007-04-17	1	-16/+16
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	The name trunk is misused as the networking term trunk means carrying multiple VLANs over a single connection. The IEEE standard for link aggregation (802.3 section 3) does not talk about 'trunk' at all while it is used throughout IEEE 802.1Q in describing vlans. The lagg(4) driver provides link aggregation, failover and fault tolerance. Discussed on: current@ Notes: svn path=/head/; revision=168793
*	Add the trunk(4) driver for providing link aggregation, failover and fault	Andrew Thompson	2007-04-10	1	-0/+289
	tolerance. This driver allows aggregation of multiple network interfaces as one virtual interface using a number of different protocols/algorithms. failover - Sends traffic through the secondary port if the master becomes inactive. fec - Supports Cisco Fast EtherChannel. lacp - Supports the IEEE 802.3ad Link Aggregation Control Protocol (LACP) and the Marker Protocol. loadbalance - Static loadbalancing using an outgoing hash. roundrobin - Distributes outgoing traffic using a round-robin scheduler through all active ports. This code was obtained from OpenBSD and this also includes 802.3ad LACP support from agr(4) in NetBSD. Notes: svn path=/head/; revision=168561
