Completed first draft of implementation of Transmit Engine. The implementation was fairly straightforward barring the calculation of CRC32(Cyclic Redundancy Check) for Frame Check Sequence.
It stalled me for a day or two requiring patience while reading and understanding the type of implementations. A very painless tutorial for understanding crc32 and its implementation from ground-up can be found here. This implementation in C also helped
Now I have generated pull request for code review.
