de75afe64f - Propagate the largest set of interface capabilities supported by all lagg 
ports to the lagg interface.
- Use the MTU from the first interface as the lagg MTU, all extra interfaces
  must be the same.

This fixes using a lagg interface for a vlan or enabling jumbo frames, etc.

b3d37ca5f8 Allow the LACP state to be queried from userland which at the moment is the 
actor and partner peer info. Print out the active aggregator and per port data
in verbose mode from ifconfig.

3bf517e389 Change from a mutex to a read/write lock. This allows the tx port to be 
selected simultaneously by multiple senders and transmit/receive is not
serialised between aggregated interfaces.

cdc6f95f84 Call if_setlladdr() on the aggregation port from a taskqueue so the softc lock 
is not held. The short delay between aggregating the port and setting the MAC
address is fine.

108fe96a44 Avoid touching various unsafe parts if the interface is disappearing. 2007-05-07 00:28:55 +00:00

d74fd34568 Change from using if_delmulti() to if_delmulti_ifma() as it simplifies the code 
and is safe to use if the ifp has disappeared.

- Refine check for lacp links, set to disabled if not suitable

18242d3b09 Rename the trunk(4) driver to lagg(4) as it is too similar to vlan trunking. 
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.
