Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

1 | The driver for the HFC-PCI and HFC-PCI-A chips from CCD may be used | ||
2 | for many OEM cards using this chips. | ||
3 | Additionally the driver has a special feature which makes it possible | ||
4 | to read the echo-channel of the isdn bus. So all frames in both directions | ||
5 | may be logged. | ||
6 | When the echo logging feature is used the number of available B-channels | ||
7 | for a HFC-PCI card is reduced to 1. Of course this is only relevant to | ||
8 | the card, not to the isdn line. | ||
9 | To activate the echo mode the following ioctls must be entered: | ||
10 | |||
11 | hisaxctrl <driver/cardname> 10 1 | ||
12 | |||
13 | This reduces the available channels to 1. There must not be open connections | ||
14 | through this card when entering the command. | ||
15 | And then: | ||
16 | |||
17 | hisaxctrl <driver/cardname> 12 1 | ||
18 | |||
19 | This enables the echo mode. If Hex logging is activated the isdnctrlx | ||
20 | devices show a output with a line beginning of HEX: for the providers | ||
21 | exchange and ECHO: for isdn devices sending to the provider. | ||
22 | |||
23 | If more than one HFC-PCI cards are installed, a specific card may be selected | ||
24 | at the hisax module load command line. Supply the load command with the desired | ||
25 | IO-address of the desired card. | ||
26 | Example: | ||
27 | There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400 | ||
28 | and 0xdc00 | ||
29 | If you want to use the card at 0xd400 standalone you should supply the insmod | ||
30 | or depmod with type=35 io=0xd400. | ||
31 | If you want to use all three cards, but the order needs to be at 0xdc00,0xd400, | ||
32 | 0xd000 you may give the parameters type=35,35,35 io=0xdc00,0xd400,0xd00 | ||
33 | Then the desired card will be the initialised in the desired order. | ||
34 | If the io parameter is used the io addresses of all used cards should be | ||
35 | supplied else the parameter is assumed 0 and a auto search for a free card is | ||
36 | invoked which may not give the wanted result. | ||
