this is the start of the transmit path. this takes packets off the
interface send queue and puts them on the hardwares tx task fifo. the tx completion path hasnt been written yet. the mbuf dmamap loading has been stolen from vic. there's obviously a lot of code that is shared between the rxf fifo loading and the txt fifo loading. i also have to think about how to better calculate and keep track of space in the fifos. this is getting harder and harder. it sucks writing tons of code without being able to verify that it works. i might take a break for a bit.
