- update to firmware version 4.1.0 - switch over to standard method for initializing cdevs (contributed by scottl@) - break out timer_reclaim_task to be per-port - move msix teardown into separate function - fix bus_setup_intr for msi-x for the multi-port case so that msi-x resources are not corrupted on unload - handle 10/100/1000 base-T media and auto negotiation - bind qset to cpu even for singleq case - white space cleanups - remove recursive PORT_LOCK - move mtu setting to separate function - stop and re-init port when changing mtu - replace all direct references to m_data with calls to mtod - handle attach failure better by not trying to de-initialize taskqueues when they have not been allocated - no longer default to jumbo frames Sponsored by: Chelsio MFC after: 3 days
