-/*
- * The 3c90x series chips use a bus-master DMA interface for transfering
- * packets to and from the controller chip. Some of the "vortex" cards
- * (3c59x) also supported a bus master mode, however for those chips
- * you could only DMA packets to/from a contiguous memory buffer. For
- * transmission this would mean copying the contents of the queued mbuf
- * chain into an mbuf cluster and then DMAing the cluster. This extra
- * copy would sort of defeat the purpose of the bus master support for
- * any packet that doesn't fit into a single mbuf.
- *
- * By contrast, the 3c90x cards support a fragment-based bus master
- * mode where mbuf chains can be encapsulated using TX descriptors.
- * This is similar to other PCI chips such as the Texas Instruments
- * ThunderLAN and the Intel 82557/82558.
- *
- * The "vortex" driver (if_vx.c) happens to work for the "boomerang"
- * bus master chips because they maintain the old PIO interface for
- * backwards compatibility, but starting with the 3c905B and the
- * "cyclone" chips, the compatibility interface has been dropped.
- * Since using bus master DMA is a big win, we use this driver to
- * support the PCI "boomerang" chips even though they work with the
- * "vortex" driver in order to obtain better performance.
- *
- * This driver is in the /sys/pci directory because it only supports
- * PCI-based NICs.
