* MFC if_lagg.c r1.20, if_lagg.h r1.11Andrew Thompson2007-10-181-0/+1
| | | | | | | | | | | | | | | | | | Fix two panics in lagg. 1. The locking was changed to shared but roundrobin mode still updated a pointer in the softc with the next tx interface to use. This will panic under high load. Change this to an atomically incremented sequence number in order to choose the tx port in round robin. 2. IFQ_HANDOFF will free the mbuf if the queue is full, this will then be freed again by lagg_start() and panic. Reorganised the error handling and freeing to fix this.

This fixes using a lagg interface for a vlan or enabling jumbo frames, etc. Approved by: re (kensmith) MFC After: 3 days Notes: svn path=/head/; revision=171661

* Rename the trunk(4) driver to lagg(4) as it is too similar to vlan trunking.Andrew Thompson2007-04-171-0/+209
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
