* Improve the EEPROM parsing, based on finding a datasheet that describesWarner Losh2008-07-092-36/+45
| | | | | | | | | | | | | | | | | | it in detail. When setting media, don't error out when a specific media is selected. # Note: There may be some issues still here since the EtherJet PC Card doesn't # conform to the datasheet. Many different kinds of dongles can be plugged in # and it is unknown how to ask which one it is. Also, add a /* bad! */ comment to a 1/2 second delay after we set the DC/DC parameters. This should be a *sleep of some sort for !cold. Fortunately it is the only one and is only used when setting media, so the benefit from removing it is small. Unfortunately, it likely serves as an exemplar of good programming techniques, which it isn't. Notes: svn path=/head/; revision=180388

| | | | | | | | | | | | | | it. Bad imp. Removing us dips us under 10,000 in size too. o Replace an unconditional 30ms DELAY (yes, busy wait) with a check of the SIBUSY bit in the SelfST register before accessing the eeprom. This changes the time to read the EEPROM from 2 * 20 * 30ms (1.2s) to < 20*25us (.0005s) and make the attach of the card tolerable when ethernet media is present. Include data from the datasheet about why this works. While this is a 2500x speed increase, it doesn't really matter at all once the card is probed... o set dev earlier in softc.

* Fix the media auto code by breaking it :-). Auto now just means 'useWarner Losh2008-06-051-19/+8
| | | | | | | | | | | | | | | 10BaseT' since it required 10BaseT to have carrier to switch to it. This chip makes it hard to do proper auto, so we don't do it. We can't test carrier on things easily. Don't insist on carrier when we set the media. Don't report failures. Remove a 1s! delay that appears to not be needed. With these patches, and John Baldwin's patches, I'm able to pass packets on my IBM EtherJet card again. Notes: svn path=/head/; revision=179553
* o Improve the probe code dealing with interrupts.Warner Losh2008-06-041-83/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | o When forced to be 10baseT, don't require that the 10baseT interface have link to succeed. Still require it for IFM_AUTO, however, since it appears that there's no way to tell if a specific type of interface worked. I'm doing a web search for a datasheet now to see if there's anything obvious. o Minor incidental formatting nits, including collapsing code of the form if (foo) { bar(); } else { if (baz) bing(); } into: if (foo) { bar(); } else if (baz) { bing(); } to save an indentation level. o Remove stray reference to 3.x config file syntax. # I believe John's patches still apply after this...

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-29/+39
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

Also, move towards bus space by introducing new macros/inline functions which make such a move much easier than before. These inline functions are setup now to work around an IBM EtherJet pccard cardbus bridge incompatibility. The card works in 8 bit mode, but not in 16-bit mode when it is connected to a cardbus bridge for reasons unknown. The Linux driver also has a similar workaround in it. Future work will include making the above workaround runtime conditional rather than compile time conditional, as well as fixing the interrupts in pccards and converting it to bus space.
