0019 This driver is developed for the SMC EtherPower series Ethernet
0020 cards and also works with cards based on the DECchip
0021 21040 (Tulip series) chips. Some LinkSys PCI cards are
0022 of this type. (If your card is NOT SMC EtherPower 10/100 PCI
0023 (smc9332dst), you can also try the driver for "Generic DECchip"
0024 cards, below. However, most people with a network card of this type
0025 will say Y here.)

0035 help
0036 Setting this value allows to align ring buffer descriptors into their
0037 own cache lines. Value of 4 corresponds to the typical 32 byte line
0038 (the descriptor is 16 bytes). This is necessary on systems that lack
0039 cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
0040 Default is 0, and range is 0 to 31.

0062 This configures your Tulip card specifically for the card and
0063 system cache line size type you are using.

0072 help
0073 Use PCI shared memory for the NIC registers, rather than going through
0074 the Tulip's PIO (programmed I/O ports). Faster, but could produce
0075 obscure bugs if your mainboard has memory controller timing issues.
0076 If in doubt, say N.

0081 help
0082 NAPI is a new driver API designed to reduce CPU and interrupt load
0083 when the driver is receiving lots of packets from the card. It is
0084 still somewhat experimental and thus not yet enabled by default.
0085
0086 If your estimated Rx load is 10kpps or more, or if the card will be
0087 deployed on potentially unfriendly networks (e.g. in a firewall),
0088 then say Y here.

0096 Use HW to reduce RX interrupts. Not strictly necessary since NAPI
0097 reduces RX interrupts by itself. Interrupt mitigation reduces RX
0098 interrupts even at low levels of traffic at the cost of a small
0099 latency.
