  82  * debug:
  83  *      NOTE: only one debug value must be given for all cards
  84  *      enable debugging (see hfc_multi.h for debug options)
  85  *
  86  * poll:
  87  *      NOTE: only one poll value must be given for all cards
  88  *      Give the number of samples for each fifo process.
  89  *      By default 128 is used. Decrease to reduce delay, increase to
  90  *      reduce cpu load. If unsure, don't mess with it!
  91  *      Valid is 8, 16, 32, 64, 128, 256.
  92  *
  93  * pcm:
  94  *      NOTE: only one pcm value must be given for every card.
  95  *      The PCM bus id tells the mISDNdsp module about the connected PCM bus.
  96  *      By default (0), the PCM bus id is 100 for the card that is PCM master.
  97  *      If multiple cards are PCM master (because they are not interconnected),
  98  *      each card with PCM master will have increasing PCM id.
  99  *      All PCM busses with the same ID are expected to be connected and have
 100  *      common time slots slots.
 101  *      Only one chip of the PCM bus must be master, the others slave.
 102  *      -1 means no support of PCM bus not even.
 103  *      Omit this value, if all cards are interconnected or none is connected.
 104  *      If unsure, don't give this parameter.
 105  *
 106  * dmask and bmask:
 107  *      NOTE: One dmask value must be given for every HFC-E1 card.
 108  *      If omitted, the E1 card has D-channel on time slot 16, which is default.
 109  *      dmask is a 32 bit mask. The bit must be set for an alternate time slot.
 110  *      If multiple bits are set, multiple virtual card fragments are created.
 111  *      For each bit set, a bmask value must be given. Each bit on the bmask
 112  *      value stands for a B-channel. The bmask may not overlap with dmask or
 113  *      with other bmask values for that card.
 114  *      Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
 115  *              This will create one fragment with D-channel on slot 1 with
 116  *              B-channels on slots 2..15, and a second fragment with D-channel
 117  *              on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
 118  *      If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
 119  *      not function.
 120  *      Example: dmask=0x00000001 bmask=0xfffffffe
 121  *              This will create a port with all 31 usable timeslots as
 122  *              B-channels.
 123  *      If no bits are set on bmask, no B-channel is created for that fragment.
 124  *      Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
 125  *              This will create 31 ports with one D-channel only.
 126  *      If you don't know how to use it, you don't need it!
 127  *
 128  * iomode:
 129  *      NOTE: only one mode value must be given for every card.
 130  *      -> See hfc_multi.h for HFC_IO_MODE_* values
 131  *      By default, the IO mode is pci memory IO (MEMIO).
 132  *      Some cards require specific IO mode, so it cannot be changed.
 133  *      It may be useful to set IO mode to register io (REGIO) to solve
 134  *      PCI bridge problems.
 135  *      If unsure, don't give this parameter.
 136  *
 137  * clockdelay_nt:
 138  *      NOTE: only one clockdelay_nt value must be given once for all cards.
 139  *      Give the value of the clock control register (A_ST_CLK_DLY)
 140  *      of the S/T interfaces in NT mode.
 141  *      This register is needed for the TBR3 certification, so don't change it.
 142  *
 143  * clockdelay_te:
 144  *      NOTE: only one clockdelay_te value must be given once
 145  *      Give the value of the clock control register (A_ST_CLK_DLY)
 146  *      of the S/T interfaces in TE mode.
 147  *      This register is needed for the TBR3 certification, so don't change it.
 148  *
 149  * clock:
 150  *      NOTE: only one clock value must be given once
 151  *      Selects interface with clock source for mISDN and applications.
 152  *      Set to card number starting with 1. Set to -1 to disable.
 153  *      By default, the first card is used as clock source.
 154  *
 155  * hwid:
 156  *      NOTE: only one hwid value must be given once
 157  *      Enable special embedded devices with XHFC controllers.
