The AIC-6915 is a bus master controller with an MII interface. It supports high and low priority transmit and receive queues, TCP/IP checksum offload, multiple DMA descriptor formats and both polling and producer/consumer DMA models. The AIC-6915 receive filtering options include a 16 entry perfect filter, a 512-bit hash table for multicast addresses, a 512-bit hash table for priority address matching and VLAN filtering. An external MII-compliant transceiver is required for media interfacing.
Multiport adapters consist of several AIC-6915 controllers
connected via a PCI to PCI bridge. Each controller is treated as a separate
interface by the sf
driver.
