21efb3cfc6 firewire: Configure channel and speed at context creation time. 
We need the channel number as we queue up iso packets for transmission
so we can fill out the header correctly.

d2746dc192 firewire: Use a buffer fill descriptor for receive when header size is 0. 
When the DMA is setup to not strip any headers, we need to use
the buffer fill descriptor instead of the dual buffer, since the
dual buffer descriptor must strip a non-zero number of header quadlets.

9aad812538 firewire: Split the iso buffer out from fw_iso_context and avoid vmalloc. 
This patch splits out the iso buffer so we can initialize it at mmap
time with the size provided in the mmap call.  Furthermore, allocate
the backing pages using alloc_page to avoid setting up kernel side
virtual memory mappings for the pages.
