> The following changes were made with this patch:
> 1. Fixed and updated the documentation a lot.
> 2. Merged lots of duplicate code into a single function
> 3. Rearranged IFF extra context structure of packet
> 4. Fixed a plane line size calculation in IFF-PBM

Since, I've decided to provide a separate patch for step 2 I just resend
the HAM support patch without doing step 2.
