fw_iso_resource_manage() - Allocate or deallocate a channel and/or bandwidth

In parameters: card, generation, channels_mask, bandwidth, allocate Out parameters: channel, bandwidth This function blocks (sleeps) during communication with the IRM.

Allocates or deallocates at most one channel out of channels_mask. channels_mask is a bitfield with MSB for channel 63 and LSB for channel 0. (Note, the IRM's CHANNELS_AVAILABLE is a big-endian bitfield with MSB for channel 0 and LSB for channel 63.) Allocates or deallocates as many bandwidth allocation units as specified.

Returns channel < 0 if no channel was allocated or deallocated. Returns bandwidth = 0 if no bandwidth was allocated or deallocated.

If generation is stale, deallocations succeed but allocations fail with channel = -EAGAIN.

If channel allocation fails, no bandwidth will be allocated either. If bandwidth allocation fails, no channel will be allocated either. But deallocations of channel and bandwidth are tried independently of each other's success.
