18 	help
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.)
26 
27 	  To compile this driver as a module, choose M here. The module will
28 	  be called de2104x.

33 	range 0 31
34 	default 0
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.

47 	  This driver is developed for the SMC EtherPower series Ethernet
48 	  cards and also works with cards based on the DECchip
49 	  21140 (Tulip series) chips.  Some LinkSys PCI cards are

58 config TULIP_MWI
59 	bool "New bus configuration"
60 	depends on TULIP
61 	help
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.
66

71 	depends on TULIP
72 	help
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.
76 	  If in doubt, say N.
77 
78 config TULIP_NAPI
79 	bool "Use RX polling (NAPI)"
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.
89 
90 	  If in doubt, say N.
91 
92 config TULIP_NAPI_HW_MITIGATION
93 	bool "Use Interrupt Mitigation"
94 	depends on TULIP_NAPI
95 	help
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.
100 
101 	  If in doubt, say Y.

123 	  This driver is for DM9102(A)/DM9132/DM9801 compatible PCI cards from
124 	  Davicom (<http://www.davicom.com.tw/>).  If you have such a network
125 	  (Ethernet) card, say Y.  Some information is contained in the file

147 	  It should work with most DEC 21*4*-based chips/ethercards, as well
148 	  as with work-alike chips from Lite-On (PNIC) and Macronix (MXIC) and
149 	  ASIX.
