      Description

      I've found some problems while testing the software download image using Alpha XGS-PON with support for the extended message set.
      @Chip help me with a private fix in the attached omci-lib-go -> software.go.
      Applying this patch in voltha 2.11, I've noticed the following error at Alpha CLI at the end of software download:

      omcid:error:owapi_rut_endSwdl:413:image crc 0xcaf9d029 in end software download does not match with the calculated image crc 0xf6715ee0

      @Chip asked me the following for further investigation:

      1) Create a binary file that is 4k bytes composed of 00->FF (see image-00-FF.bin).
      I've improved openonu logs to print all section data to be sure that the slice contains the true data (rawdump and omci.hex).
      I could say that the slice seems to be good, as follows:

      . 1st section data: from 00 -> ac
      . 2nd section data: from ad -> 59
      . last section data: from 5a -> ff (smaller fragment)

      Besides that, he asked me to try some tests that I did not started:

      2) Set window size t 1 and send every request asking for an ack response

      3) Pad the very last frame out, with zeros

      Regards,
      Marcos
