Jak na full duplex?

[CompCrasher]

Mam sitovku 3Com (ISA) s modulem 3x509 (tim 3x si nejsem jist, ale od 3com s 509 nakonci je jen jeden). Pokazde mi linux nastavi half-duplex... ... Jak nastavit full?? thx

The following are notes and information on using the 3Com EtherLink III series                                                                                          
ethercards in Linux. These cards are commonly known by the most widely-used

The v1.18c driver added support for the 3c509B's full-duplex capabilities.                                                                                              
In order to enable and successfully use full-duplex mode, three conditions                                                                                              
must be met:                                                                                                                                                            
                                                                                                                                                                        
(a) You must have a Etherlink III card model whose hardware supports full-

positively known to support full-duplex are the 3c509B (ISA bus) and 3c589B                                                                                             
(PCMCIA) cards. Cards without the "B" model designation do *not* support

3c589, the 3c529 (MCA bus), and the 3c579 (EISA bus).                                                                                                                   
                                                                                                                                                                        
(b) You must be using your card's 10baseT transceiver (i.e., the RJ-45                                                                                                  
connector), not its AUI (thick-net) or 10base2 (thin-net/coax) interfaces.                                                                                              
AUI and 10base2 network cabling is physically incapable of full-duplex                                                                                                  
operation.                                                                                                                                                              
                                                                                                                                                                        
(c) Most importantly, your 3c509B must be connected to a link partner that is                                                                                           
itself full-duplex capable. This is almost certainly one of two things: a full-                                                                                         
duplex-capable  Ethernet switch (*not* a hub), or a full-duplex-capable NIC on                                                                                          
another system that's connected directly to the 3c509B via a crossover cable.                                                                                           
                                                                                                                                                                        
/////Extremely important caution concerning full-duplex mode/////                                                                                                       
Understand that the 3c509B's hardware's full-duplex support is much more

at the physical layer of the network it fully supports full-duplex operation,                                                                                           
the card was designed before the current Ethernet auto-negotiation (N-way)                                                                                              
spec was written. This means that the 3c509B family ***cannot and will not

circumstances, no matter how it is initialized***. If the full-duplex mode

independently _forced_ into full-duplex mode as well; otherwise various nasty                                                                                           
failures will occur - at the very least, you'll see massive numbers of packet

would ever be necessary or desirable.

a jeste cast overriding card's settings:

The driver allows boot- or load-time overriding of the card's detected IOADDR,                                                                                          
IRQ, and transceiver settings, although this capability shouldn't generally be                                                                                          
needed except to enable full-duplex mode (see below). An example of the syntax                                                                                          
for LILO parameters for doing this:

Jasne je to napsany i na ty sitovce: 3C509B- TPO... Modul uz je i zavedenej... Ale nejak sem se nedocet jakze to vlastne nastavim, kdyz to ted jede na half duplex.... thx

EDIT: sorry, uz to vidim

[Wohmatak]

tady je to hezky zdokumentovany

btw tu posledni cast sem tam pridaval az chvili pote ale jinak je to standartni dokumentace ke zdrojakum kernelu...

edit: a pro nadsence je tu patch pro kernel

[CompCrasher]

Hmm, napsal jsem to jak spousteci parametr lila... Kdyz server ukoncim, vypnu, uz nepise nic kolem half duplex.... Akorat : setting Rx mode to 0 adresses..... Ale to chapu jako nejaky zpusob preruseni Rx prijmu dat.. Asi

[Wohmatak]

jak ukoncim server?
btw pustil si "lilo"?

[CompCrasher]

Zapomel sem pripsat ten vypis z lila... Nejak to asi nepoznalo co to po nem chci.... Hodilo to error, o "ether"

btw: tenhle prikaz se stejne pouzivat jen u toho ovladace vyse, ne?

procetl sis ten link na scyld.com co sem daval?

jinak ten parametr do jadra se zadava asi obecne, jde o to jestli to ostatni ovladace sezerou.... a mozna musis mit ovladac zakompajlenej do kernelu?

[CompCrasher]

Dik moc... zkusim to pozdejc... Kazdopadne stahnu ten zdrojak, nainstaluju ho jako modul..... A pak se uvidi.. Mimochodem,

ether=10,0x310,3,0x3c509,eth0

zde ma byt 4ka...-10baseT (3ka je pro 10base2)

ale jinak dik moc!
