[linux-dvb] DVB Card MAC address

[Kápolnási Tamás <ktamas@tdc.hu>]

Hello!


How I know writing DVB card MAC address to file?
(The dvb driver writing to stdout, when the load up kernel module)


I found the source code in ttpci-eeprom.c:

>         memcpy(i2c->adapter->proposed_mac, decodedMAC, 6);
>         dprintk("%s adapter %i has MAC addr = %.2x:%.2x:%.2x:%.2x:%.2x:%.2x\n",
>                 i2c->adapter->name, i2c->adapter->num,
>                 decodedMAC[0], decodedMAC[1], decodedMAC[2],
>                 decodedMAC[3], decodedMAC[4], decodedMAC[5]);


I'm not developer, but i try:
