  19           This driver is developed for the SMC EtherPower series Ethernet
  20           cards and also works with cards based on the DECchip
  21           21040 (Tulip series) chips.  Some LinkSys PCI cards are
  22           of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
  23           (smc9332dst), you can also try the driver for "Generic DECchip"
  24           cards, below.  However, most people with a network card of this type
  25           will say Y here.)

  35         ---help---
  36           Setting this value allows to align ring buffer descriptors into their
  37           own cache lines. Value of 4 corresponds to the typical 32 byte line
  38           (the descriptor is 16 bytes). This is necessary on systems that lack
  39           cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
  40           Default is 0, and range is 0 to 31.

  62           This configures your Tulip card specifically for the card and
  63           system cache line size type you are using.
  64
  65           This is experimental code, not yet tested on many boards.

  73           Use PCI shared memory for the NIC registers, rather than going through
  74           the Tulip's PIO (programmed I/O ports).  Faster, but could produce
  75           obscure bugs if your mainboard has memory controller timing issues.

  80         depends on TULIP
  81         ---help---
  82           NAPI is a new driver API designed to reduce CPU and interrupt load
  83           when the driver is receiving lots of packets from the card. It is
  84           still somewhat experimental and thus not yet enabled by default.
  85
  86           If your estimated Rx load is 10kpps or more, or if the card will be
  87           deployed on potentially unfriendly networks (e.g. in a firewall),
  88           then say Y here.

  96           Use HW to reduce RX interrupts. Not strictly necessary since NAPI
  97           reduces RX interrupts by itself. Interrupt mitigation reduces RX
  98           interrupts even at low levels of traffic at the cost of a small
  99           latency.
